Is solar energy storage expensive?

The cost of solar power has fallen by 87%, and battery storage by 85% in the past decade, according to a new study – here’s why.

Berlin-based scientific think tank Mercator Research Institute on Global Commons and Climate Change (MCC) has released a new study in the journal Energy Research & Social Science in which the researchers compared the corresponding findings from innovation reports with the standard model-based scenarios on climate transition. They found that despite the ongoing use of fossil fuels and biomass in the near future, clean energy is ultimately going to change the energy game.

The study focuses on solar and battery storage, but the researchers note that wind power, heat pumps, and other clean technologies are also seeing a sharp drop in prices, too.

Technological advances are making solar and battery storage smarter and more efficient. Globally, production of solar components and battery storage are being ramped up commercially, and that’s being spurred on by both private and public financial backing and government policy support in response to the global effort to limit global warming to well below 2C. And as a result, the clean energy industry’s economy of scale is causing prices to plummet.

When clean energy is deployed, electricity prices drop. Lead author Felix Creutzig of the MCC said:

Some calculations even suggest that the world’s entire energy consumption in 2050 could be completely and cost-effectively covered by solar technology and other renewables.

This is an extremely optimistic scenario – but it illustrates that the future is open. Climate science, which provides policymakers with guidance in its scenario models, must reflect technical progress as closely as possible. Our study is intended to provide input for this.

For example, the study notes, battery storage already cost less than $100 per kilowatt hour, which is significantly less than was predicted for 2030 in a study two years ago. They assert that the price premium for battery storage will drop from 100% at present to only 28% in 2030. 

And in 2050, experts expect 63,000 terawatt hours of solar energy to be available globally – that’s twice as much clean energy as is supplied by coal today. And 80% of private investments in new energy capacity are now fossil-free. 

The researchers point out, however, that coal is still hanging around like a bad smell because “considerations such as jobs, tax payments, political constraints, or financial liquidity keep governments investing in coal even when renewables actually have a better pay-off.”

Jan Minx, head of the MCC Applied Sustainability Science working group and one of the study’s co-authors, said:

Greenhouse gas emissions are higher than ever and the measures taken so far are too weak, but in this politically difficult situation, technological progress provides a ray of hope.

New scenario models, some of which are starting to be explored, are likely to demonstrate in the foreseeable future that the global climate transition might not be as expensive as previously assumed, and may even be cost saving – provided it is finally tackled.

How Much Does Solar Storage Cost? Understanding Solar Battery Prices

When using solar energy, one often has to be mindful of solar storage cost. As the price of energy continues to increase manifold, a lot of them have turned to solar power. Storing the excess solar power to utilize at night time  is a common practice  these days.

Understanding the battery size

Before determining the cost of solar storage and the price of a solar battery, it is first important to understand the wattage and power that would be required for the home. The pricing would depend a great deal on the power output chosen. Mostly, it is seen that the price of solar battery storage tends to start from $5000 while if you have a bigger home and more energy requirements, the cost could shift up to $10000 a year or even more as well.

Smaller requirements

When solar energy is simply needed to be stored so it could be used later , when the appliances cannot tap the sunlight any more, one can do with smaller battery like the Enphase. Here, the cost would be less but then again, this won’t light up all the points and it won’t help you have a completely solar home. Those who want to have their home run entirely on solar power with the provision of backup as well, they will need to opt for larger battery. This would definitely entail a significantly higher cost. But when you compare it with the electricity cost otherwise in the long run, it might end up being a smarter choice. There are a lot of people who are skeptical about setting up solar powered homes simply because of the initially high installation cost. However, there are lease options available to deal with the high initial expenses. Over a period of time, the energy output and the cost of solar power ends up balancing the massive initial expense and might even turn out to be an economical choice in the long run.

Here is a rough idea for the pricing of solar battery

The enphase AC battery of size 1.2 kWh would cost $2000 which comes fully installed. Soltaro 2 (2 kWh) and Pylontech US2000B (2.4 kWh) cost even less and are priced at $1700 and $1999 respectively. All other options tend to cost more as the SolaX 3.3 with a power of 3.5kWh is going to cost $5390 and the Akasol neeoQube with a power rating of 5.5 kWh can set you back by as much a $12000. So, solar battery cost is directly dependent on the battery size and power and one should make it a point to determine the cost and efficiency trade off and decide the form of electricity they wish to install at their home.
