Frequntly Asked Questions?
How long do solar panels last?
Our solar panels are built to last 25 to 30 years. Even after that period, they continue to produce energy efficiently, though with a slightly lower output (around 85–90% of the original capacity).
Can I change or cancel my booked advice call?
Yes, you can easily reschedule or cancel your appointment through the confirmation email or by contacting us directly via WhatsApp or phone.
What is the average payback time for a solar system?
Most customers recover their investment within 5 to 7 years, depending on energy usage, panel orientation, and current electricity tariffs. With rising energy costs, the payback period can be even shorter.
Can Voltera help me apply for subsidies or financing?
Yes! We guide you through all available options, including regional grants, the Warmtefonds loan program, and the Dutch VAT refund on solar installations. Our team ensures the process is smooth and fully compliant.
How does a home battery work with solar panels?
A home battery stores excess solar energy during the day so you can use it in the evening or during power outages. This helps you become more energy-independent and increases your savings.
Do you also install heat pumps and air conditioning systems?
Absolutely. In addition to solar panels and home batteries, Voltera provides heat pumps, hybrid systems, and air conditioning units — all designed for high efficiency and sustainability.
Do you offer maintenance services?
Yes, we offer optional maintenance packages that include annual system inspections, performance monitoring, and cleaning to ensure your system operates at maximum efficiency.
