Frequently Asked Questions

How much can you save with solar batteries?

One of the most attractive features of solar batteries is the potential for long-term savings. While the initial installation cost may seem high, most homeowners experience significant reductions in their energy bills. Robinsun solar batteries are very affordable, providing the best quality available in the market. With two Robinsun solar panels positioned at 20 degrees in Spain facing south, they are estimated to produce 1.951 kWh per year. Your annual savings would be calculated by multiplying by the electricity price (the average price in Spain in 2024 is €0.23), which equals approximately €458. With a smart meter installed in your solar battery system, any surplus energy that you produce doesn’t go to the grid; you can keep it all and use it later, allowing you to save even more each year.

What is the environmental impact of solar batteries?

Solar batteries are a great option for a clean and renewable energy source. By using solar energy, you reduce your reliance on fossil fuels and decrease your carbon footprint. Solar energy produces no greenhouse gas emissions, making it one of the most environmentally friendly energy options available today. We are proud to have achieved a climate impact certification for our plugin solar kits. A plugin solar kit with two solar panels in Spain saves 340 kg of CO2/year, for at least 30 years! They benefit you both in terms of savings on your power bills and in CO2 saved by producing your own solar energy. This certification, granted by certification company Impact Forecast BV, an independent and neutral third-party company, marks a significant milestone in Robinsun's journey toward reducing our customers’ carbon emissions and contributing to a greener future.

Can I be energy-independent with solar batteries?

Solar batteries allow you to generate your own electricity and store it, reducing your dependence on the grid. This is particularly beneficial during times of energy shortages or rising electricity prices. With solar batteries, you take control over your energy usage and costs.
