These are among the questions we are asked most often about solar.

How do Solar Panels work?

Solar panels allow photons, or particles of light, to knock electrons free of atoms, generating a flow of electricity. They work by absorbing sunlight with photovoltaic cells, generating Direct Current (DC) energy. They convert it to Alternating Current (AC) with an inverter. AC then flows through the home’s or business’ electrical panel to be distributed throughout the building. The more sunlight they collect, the more energy they produce.

What are Solar Panels made of?

Solar panels are made of small units of photovoltaic (PV) cells which convert sunlight into electricity.

Each cell is made up of two layers of semiconducting material.

They are black in color, perfect for absorbing heat and light. Many cells linked together with electrical wiring make up a solar panel.

Can I install solar panels now and add battery storage later?

Yes, you can. Solar systems can be installed with special inverters that can be attached to solar energy battery storage units at a later time. This is called a ‘storage retrofit,’ and it is a great way to prepare for adding solar storage options in the future.

How long will my solar array last?

Most solar panels come with a 20-year warranty. We have installed many systems that have outlived their warranties and are still performing well.

Will my system need maintenance?

Solar is a simple, almost maintenance free technology. You should not have to replace your panels during their warranty lifetime. However, the wiring that connects your panels may need to be checked occasionally to make sure it has not been tampered with by wildlife.
