Solar panels can be a good choice for homeowners today. They offer a free form of energy that is also clean and produced without any emissions, pollutants, or other damage to the environment. In some cases, homeowners may also be eligible for rebates and other incentives from the government when they install solar panels at home. If you're considering this option for your own home, you might have some questions about how they work and their maintenance. Note a few of those here.

1. Do solar panels need maintenance?

Rarely do solar panels need any type of maintenance or upkeep. They typically do not need adjustments of any sort. In some cases you may need to brush off the solar panels if there is a buildup of leaves and snow or other debris, but this is usually a very quick and easy job and doesn't require any special tools, other than a soft-bristled broom that won't scratch the panels.

2. Do solar panels work in the wintertime and at night?

Solar panels are like batteries in that they store energy; they don't simply operate when the sun is shining and then 'switch off' at night. However, it is good to note that during very long winters or other times when sunlight is scarce, the solar panels may not collect enough energy to provide all your electrical needs. Many people find that having standard electrical wiring through their city's grid is still needed even with solar panels, but this electricity is used only when the power stored in the solar panels gets depleted.

3. Is there a permit needed to install solar panels?

In most areas, you will need a permit to have solar panels installed. If you work with a contractor, he or she can usually obtain those permits for you or direct you to the right office to call to get them on your own. Don't hesitate to ask for their assistance.

4. Why not install solar panels yourself?

You may be legally allowed to install solar panels on your own, but like many home improvement projects, this job is often more difficult than you realise. Solar panels need to be facing the direction that will afford them the most sunlight, and they then need to be wired into your home's electrical circuits. You don't simply put solar panels on your roof, screw them into place, and then plug something into a wall outlet. Because of the details of this job, it may be best to leave it to a professional installer.
