Solar Systems

How do solar panel systems work?

SolarTech solar panels are designed to harness the power of the sun and convert it into electricity. Solar panels are made up of many small solar cells that are connected together. When the sun shines on the solar panel, the solar cells absorb the sunlight and generate an electric current. The amount of electricity that is generated depends on the size of the solar panel and the strength of the sunlight. Solar panels can be used to power homes, businesses, and even farms.

Do solar panels produce power when the sun isn’t shining?

Solar panels are a great way to generate renewable energy, but many people are concerned about what happens when the sun isn’t shining. Solar panels actually produce power even when the sun isn’t out, but the amount of power generated is reduced.

What happens if there is snow on solar panels?

Most solar panels are designed to be installed at an angle, which allows snow to slide off more easily. However, a heavy accumulation of snow can block the sun from reaching the panel and prevent it from generating power.

How long will my solar power system last?

There are various components that go into keeping a well-maintained solar system, but for the most part, solar panels are very durable and can generate electricity for 25-35 years. 

Solar Tax Credit

What is a tax credit?

A tax credit is an amount of money a taxpayer can subtract from the total amount of taxes they owe. For example, if a taxpayer owes $1,000 in taxes and has a $200 tax credit, they would only owe $800. Tax credits can be earned for a variety of reasons, such as completing an energy-saving home improvement or being a low-income earner. Some tax credits are even refundable, which means that the taxpayer would receive a refund if the credit exceeds the amount of taxes owed. Tax credits are generally considered to be more beneficial than tax deductions because they reduce the amount of taxes owed dollar-for-dollar. 

What is the federal solar tax credit?

A federal solar tax credit is a tax credit that can be claimed on one federal income tax for a percentage of the cost it took to install the PV system.

Solar PV systems that were installed in 2020-2021 are eligible for a 26% tax credit and as of August 2022, Congress passed an extension of the ITC, raising the tax credit to 30% when installation is performed between 2022-2032. Once the year 2033 hits, the tax credit will decrease to 26%, and in 2034 even further down to 22%. The tax credit is predicted to expire starting 2035 until further notice from congress.
