We’re always thrilled to hear how our plugin solar kits make a real difference in our customers' lives. Recently, we received an inspiring testimonial from José, a homeowner in Madrid who installed a 800 W Robinsun plugin solar kit at the start of 2024. This testimonial explores the significant impact the kit had on his energy bills over the first few months of use, highlighting the financial and environmental benefits of going solar and how the results are confirmed month by month.

Background and early impact

After experiencing rapid increases in electricity bills and charges over the past months, José decided it was time for a change. Rising electricity costs and VAT changes, with monthly bills fluctuating between €75 and €95, prompted him to research sustainable alternatives with solar energy. After encountering difficulties to find a rooftop solar installer for his Madrid home, his search led him to Robinsun and our self-installable Performance 800 W plugin solar kit.

In the last week of January 2024, José took the decision to install his Robinsun plugin solar kit. He was drawn not only by its easy self-setup and potential for immediate savings but also by the unbeatable price-to-quality ratio that Robinsun offers. Unlike other providers, Robinsun's kits are designed for optimal performance right out of the box, ensuring that customers get the most out of their investment from day one. The results were evident just a month later, in February, when his electricity bill dropped to under €40—a nearly 50% reduction.

With his kit producing a stable amount of electricity during the day, especially on weekends when more devices were in use at home José noticed that his peak consumption had dropped. Checking the installed power that his electricity provider was invoicing every month, he noticed that peak consumption never got even near the amount he was paying for. This led him to request a reduction of installed power, lowering the fixed costs part of his monthly invoice, on top of the lower variable cost part for his actual consumption.

When we launched our certification services at the end of march 2024, José was among our first customers to get his installation certified. With the CIE he received, he notified his power company to request compensation for the surplus energy his kit produced during a few hours of the day, when he consumed less than the kit produced.

José’s savings grew even more in March 2024, when the CIE benefit came into effect, further reducing his bill to just under €25. This marked a 65% decrease in electricity bills compared to life without a plugin solar kit. By June 2024, with long sunshine hours during the summer months in Spain, his bill dropped to under €20—a 75% decrease.

Summary of savings

Conclusion

This testimonial from Madrid illustrates the tangible benefits of investing in a Robinsun plugin solar kit seen throughout several regions and countries in Europe. José experienced a dramatic reduction in his energy bills, starting with a 50% decrease in the first month and reaching a 75% reduction by June 2024. These savings not only eased the financial burden of rising electricity costs but also contributed to a more sustainable lifestyle of Jose’s family. José tells us his spouse said “it feels good to know you’re not doing anything bad every time you turn the light on.”
