Frequently Asked Questions
How do solar panels generate electricity?
Solar panels contain photovoltaic cells that convert daylight into direct current (DC) electricity. An inverter converts this into alternating current (AC) for use in your property, with any surplus either stored in a battery or exported to the grid.
Can solar panels reduce electricity bills?
Using electricity you generate yourself can reduce the amount you buy from the grid. The level of any saving depends on your system, usage, tariff and property, so we do not guarantee specific savings.
Do solar panels work during winter?
Yes. Panels generate electricity from daylight rather than heat, so they continue to work in winter and on cloudy days — although output is lower than in summer due to shorter days and weaker light.
Do I need battery storage with solar panels?
No — solar panels work without a battery. A battery lets you store surplus generation for later use, which can be helpful if you use most of your electricity in the evening.
How long does installation take?
Many domestic installations are completed within one to two days once access is in place. Commercial installations vary according to scale.
What warranties do you provide?
Nassau Electric League offers 12-year warranties for solar and battery installations, with full coverage details provided as part of your quotation.
