10 Questions to Ask A Solar Company Before Going Solar

Oct. 14, 2022

Installing solar panels is a safe investment with a high return for Massachusetts homeowners. But as with any major investment, it’s important to do your research before making a final decision. Getting answers to all your questions before going solar will help you make the best decision for your home and ensure you receive the highest return on your investment. 

Here are 10 questions to ask before installing solar panels in Massachusetts: 

1. How do solar panels work? 

Before investing in a solar panel installation, you should learn a little bit about how solar panels work. You don’t have to master all the technical details, but having a basic understanding will be extremely helpful as you move forward with your solar journey. 

Here’s an overview of how solar panels produce energy: 

1. Solar photovoltaic (PV) panels absorb sunlight, creating an electric current. 
2. The current is directed toward an inverter, which transforms it into usable electricity. 
3. The electricity is sent to your electrical panel and distributed throughout your home. 
4. Excess electricity is either sent to the grid or stored in a solar battery. 

2. Is my house right for solar? 

Almost any homeowner in Massachusetts can benefit from solar panels, but some houses are better suited to a rooftop solar installation than others. Before you install a home solar system, you should consider which direction your roof faces (south-facing roofs are typically best for solar panels), how much roof space you have available, and whether there are any shading concerns like surrounding trees. 

3. How much money will I save with solar panels? 

Solar panels save you money on your utility bills by allowing you to produce your own electricity. But before you invest in a home solar system installation, you should make sure your electricity bill is high enough to justify going solar. 

In most cases, installing solar panels makes financial sense–as long as you’re using an average amount of electricity, you’ll save money with solar panels. If your electric bills are about $50 or less, however, solar might not be worth it for the electricity bill savings alone, unless you’re planning to electrify your home. 

4. Should I install solar batteries? 

Solar batteries are becoming increasingly popular among homeowners, and you’ll want to consider installing them when you go solar. It’s possible to add solar batteries after you install solar panels, but it’s easier and more affordable to install them at the same time. 

Solar batteries will add to your solar installation costs, but the benefits are worth it. With battery storage, you’ll be able to keep your solar panels on during a grid outage, helping you avoid blackouts. Batteries can also be used as a backup power source at night, so you can use more clean energy.  

5. How much do solar panels cost? 

You can’t make a decision about installing solar panels until you know how much it’s going to cost. Unfortunately, there isn’t a one-size-fits-all answer to this question. Home solar installation costs can vary significantly depending on how much electricity you use, the slope and design of your roof, the type and number of panels you want to install, whether you include solar battery storage, and many other factors. 

Scheduling a consultation with a reliable solar installer near you is the best way to get an accurate solar installation cost estimate. At Boston Solar, we analyze your home and your recent electric bills so we can provide the most accurate quote possible. 

6. Do solar panels qualify for tax credits? 

There are several solar incentives available to make home solar and battery installation more affordable, and you don’t want to miss out on any! Finding out which rebates and incentives you qualify for will help you get the best deal on your solar installation. 

Home solar and battery installation qualifies for the federal solar tax credit. With the credit, you can get a tax break worth 30% of your total costs, making solar panel installation and ownership significantly more affordable. Other incentives, like net metering, SMART, and ConnectedSolutions, can make your solar installation even more financially rewarding. 

7. Can I finance my solar panels? 

Nearly all residential solar installation companies offer financing and many homeowners take advantage of it. Financing makes it easier to pay for a solar installation and is a much better option than leasing solar panels. When you finance your solar energy system, you are its owner and remain eligible for all applicable tax breaks and incentives. 

Boston Solar can speak to financing options to help you get past the hurdle of upfront solar installation costs. 

8. Do solar panels come with a warranty? 

Most solar panels come with a manufacturer’s warranty and, depending on the installation company, a workmanship warranty. Solar warranties give you peace of mind and help protect your investment in solar energy. 

At Boston Solar, we back our installations with a 25-year solar panel and inverter warranty and a 10-year workmanship guarantee. 

9. How much experience does your solar installation company have? 

When you’re researching solar companies near you in Massachusetts, experience is an important factor to consider. You want to make sure the installer you choose knows what they’re doing and won’t be using your solar panel installation as a practice run. 

Boston Solar has been in business for more than 10 years and installed over 5,000 solar energy systems. We know the ins and outs of solar installation in Massachusetts and will take care of your project seamlessly, from system design and permitting to installation, net metering application, and grid interconnection. 

10. Can you provide testimonials? 

Reading reviews and testimonials is one of the best ways to vet a solar company and decide whether you want to work with them. Past customers can provide valuable insights that you won’t get from company representatives. 

Boston Solar has a 4.8-star rating with over 800 Google reviews. We encourage you to read our customer testimonials and take a look at our completed residential solar projects to see why so many Massachusetts homeowners have trusted us with their solar panel installations.

Buying a solar system can be exciting but it’s also a huge investment. So before you dive in, you need to be as informed as possible about solar panels and other important aspects of your purchase.

1. Should I buy a solar system?

The cost of installing solar has been reducing over the past five years and will continue to become cheaper. However, the cost of waiting for further reductions is the increasingly expensive electricity bill that you pay your energy retailer. Right now you are effectively ‘renting’ your electricity and in five years you will have nothing to show for the thousands of dollars you have parted with. Should you then decide to purchase a solar system, the system price may be cheaper but when you add your aggregated energy bills you have paid to this price you find it very expensive indeed!

If you invest in solar now you become an energy ‘mortgagee’. You now own a big share of the electricity you consume and your savings start immediately to pay off your investment cost. In five years or so, your power savings have now paid off the cost of your investment. You now own your energy production outright and with a top tier REC solar system you will continue to make savings for a further 25 years at least.

Right now the power companies have secured the right to increase their rates by 25% annually over the next three years. Based on this rate your power bill is tipped to double! With the arrival of solar battery storage now is the time to start investing in solar and take control over your power bills.

Please also take note. There is still a solar government rebate available in all states and territories, and even though it is less than what used to be available in the past, on a 5 KW system for example you are likely to receive over $2,800-$2,900 in rebates.

Some solar installation companies offer financing options, which could reduce your initial outlays. This will allow you to use the electricity cost savings to help finance the repayments.

2. What makes a good quality solar system

A solar power system has a number of considerations to ensure customers are satisfied for many years:

• The solar panels purchased should be from a known and diversified manufacturer, so in future years you can receive follow up service or warranty back up, as the company is still around. Some solar manufacturers are currently in financial distress. Just read up on the internet about these issues.
• Only use high quality inverters with your system. The inverter undertakes the key work in your system. Every time there is a cloud and change in weather the inverter adjusts the output. Therefore an inverter never stops during the day. High quality brands which work well with your REC panels can be recommended by your local REC installer. Please avoid cheap inverters.
• Framing systems. There is no point buying quality panels and inverter and not fastening them with a quality framing system. E-Smart Solar can provide you with solid advice.

3. What is the expected lifespan of a solar power system?

The key components susceptible to failure are the solar panels and inverter. However, high quality products tend to have long life cycles which are reflected in the long warranties available, particularly for solar panels.

A solar panel is a relatively simple device with no moving parts. Solar panels typically have a 25 year output warranty and depending on the quality of the panel can be expected to last beyond this. Also solar panels which are exposed to wind, fluctuating temperatures and weather do deteriorate and each year produce a little less electricity. Cheaper panels, with less UV stabilized backing sheets, cheaper sealants and framing can deteriorate faster and more rapidly.

4. Why should I choose a good brand solar panel?

Arguably, the quality of your solar panels and the inverter are the most crucial factors in selecting a solar system. Over their 25 year output warranty period, solar panels will be subjected to more than 100,000 hours of relentless sunshine, extremes of heat and cold, wind, rain, hail and more. Australia and New Zealand offer an extraordinarily harsh climate for an electrical device.

A good brand like REC, with our extensive testing and quality control helps ensure that you get the most out of your system over its long operating life.

5. When should I NOT buy a solar system?

Most of homes or business premises in Australia can install a system but there are times when you should not buy a solar system. For example:

1. You have no roof space available which is facing North, North East, North West, West or East
2. There is strong shading of trees and building most of the day on your North, East or West facing roofs. Is there is a little shading for part of the day micro inverters or optimisers can offer a solution.
3. You have an asbestos roof
4. When the system has to be installed at a distance from the home (like at farm sheds) and the additional cost of running the electricity wires and poles back to the meter far outweighs the return on investment
5. You are out of your house/premises most of the time, therefore you cannot use the solar power when it is generated. The unused solar power will be exported to the grid. On average your energy retailer will credit you 11c  per kW, making the investment in solar financially less attractive. In this case solar would only be suitable if you also install a battery storage system.

6. As a consumer, what are my rights so I am assured it is a safe investment?

When you purchase a solar system you are protected by a variety of rights, warranties and acts as a consumer.

The overriding protection comes from the Australian Consumer Law which came into effect in January 2011. This Federal Act provides protection for all consumers and is administered at a State level. Businesses are required by law to comply with the requirements of this act and it specifies where responsibilities lay, what rights consumers have and how to take action.

There are several specific issues described in the act which offer protection that is most relevant to solar system owners. They are summarised below:

When you agree to purchase a system, the company you sign a contract with is the first point of responsibility for all issues. They are the prime contractor in law, although they may subcontract some work such as installation and must ensure that all standards, laws and regulations are adhered to by their staff and their sub-contractors.

If you buy imported equipment, the warranty responsibility ultimately lays with the official importer, so it’s important to understand who that is, if it’s not your supplier. That’s why picking brand panels like REC offers you solid protection. However, should you decide to buy a cheaper panel and the manufacturer disappears, or the importer has gone bankrupt, the prime contractor has still a legal obligation to assist you.

Warranty terms and conditions vary by contract and supplier. It is important that you carefully read and compare the terms and conditions from different suppliers so you understand what you may be required to do to comply. For example many panel warranties only include the supply of a new panel. They do NOT include the labour component. REC supplies the panel and pays for the labour within 80 km of population centres.

In the event of a dispute, the Clean Energy Council can assist you with installer related issues. They also have a Solar Retailer Code of Conduct which some, but not all solar retailers have agreed to comply with.

In most cases, if there is a dispute that is unresolvable by discussion, the issue will default to the Australian Consumer Law act and you can approach your State body for advice on what course of action to take. This may include mediation, taking the case to the Small Claims Tribunal or to court.

7. What size panels should I buy?

There are various sizes of solar power panels available. The higher the output, the higher will be the efficiency of the solar panel (as long as the size of the solar panel is the same – of course). A number of years back the 170W to 190W solar power panels were considered a high wattage panel.

Today the technology has improved so that 260W panels are considered a good solid efficiency as more solar power can be produced in a smaller roof space.

Nevertheless some higher efficiency panels can offer a shorter return on investment period.

8. What should I check in a quote before I buy a solar power system?

Make sure the installer comes to your house and has a look, before you get the quote. Internet based solar companies quote you for a system over the phone can spell trouble for the install quality, as they cannot truly appreciate the individual set up of your house. Are the tiles brittle? Where are any surrounding trees, which can cause overshadowing? What about antennas and chimney locations – which in the future through overshadowing can affect the system output significantly? How old is your switch board and does it need upgrading to handle solar? All these questions only become clear through a proper home inspection.

When internet or call centre based solar companies sell you a system they use the one size fits all approach and give you a standard price. They then negotiate with a sub-contract installer to install your system for an agreed price. So the sub-contracted installer holds all the risk should your system requires extra cabling or is a particular labor intensive installation. It is more likely in this situation for the installer to find the quickest way, not necessarily the best way to install the system. Being a sub-contractor to the company that sold you the system, the installer’s relationship with your system is one of “get in and get out as quick as possible”.

Should you, in the years to come require support for your solar system, the internet based solar company might not be around anymore, or should they still exist are very likely to send a new sub-contractor to check out the issue. It is better, like with your car, to have the same reliable mechanic undertake the ongoing work. Someone who is familiar with your particular circumstances/system.

In general the quotation should provide solar system specifications like quantity of panels, brand and model of panels, system size and likely output per annum in kW/h, capacity and output of the inverter or if micro inverters are to be used the brand and warranty conditions.

A proper, considered quote should include also datasheets of the supplied products. In general make sure your quote includes:

• • Solar PV modules – brand, model and manufacturer’s warranties;
  • Mounting frames – brand, warranties and which part of the roof to be installed;
  • Inverter – brand, capacity and manufacturer’s warranty;
  • Any additional metering cost – if not included in the price, make sure this aspect is clearly outlined in the quote;
  • Travel and transport requirements if not included;
  • Any trench digging if solar to be installed on outbuildings e.g. farms.
  • At hand over, make sure the installer gives you a system user manual.

The quotation should also specify a total price, together with proposed start and completion dates. The quotation should form a basis for your contract with the designer/installer. Deposit requirements for the system by law should not be more than 10 per cent. Usually the majority of the solar system needs to be paid for on the day of installation.

9. What are the ongoing costs of running a solar power system?

It is advisable to organise some maintenance inspections every few years to make sure that all parts of your solar electric power system are operating correctly. With a tilt angle of 10 degrees or greater solar panels are self cleaning. If you install panels onto a flat roof without panel tilts you will need to hose down your panels every couple of months.

10. Is my solar power system insured?

Most home and building insurance policies cover home solar systems on roofs and garages. A solar electric power system is just like the hot water system an extended part of the home.

However most insurance companies would like to be contacted so that you can let them know you added your solar electric power system. Make sure you let them know the value of the system (before rebates) so they will know the actual replacement cost.
