The Custom Quote

Before you can even begin your solar installation, a solar estimator will visit your property to inspect your home and your roof. They will ask what your energy goals are and your roof inspection is to make sure your roof can hold your solar panels. 

Once you decide to hire the company, they will send out a surveyor to make sure nothing will be missed. The engineers will then design your very own system and make sure everything is correct from the measurements, the solar panels location to the electrical system. 

Permits & Documents

Installing solar means a lot of paperwork. The good thing is if you hire a solar company the will be the ones who will handle it. It’s never a bad idea to know what are the steps and know what’s going on. 

Make sure to understand all of the rebates and incentives such as the 26% Federal tax. Building permits will also need to be filled out, but it might depend on the state and area you live in. For example, in certain states you can install solar panels on your entire roof, other states and counties you need some clearance.

Installation Day

The most exciting time of the process. Your installers will prepare your roof to make sure the roof is secure and strong. Then they will start with the electrical part to be able to connect your panels to the electric panel.

Once that is done the rack or rails will be installed, this will support the panels and make it secure, safe and leveled. 

Last but not least, the inverter installation. These devices will convert your DC (direct current) into AC (alternating current) which is the type of energy that your home uses. The energy will connect to the grid.

The installation process depends on the size of your system, but it typically takes 1-3 days for the whole system to be installed. 

Seal of approval

The last and final step is for your system to be inspected by the city. Once your local government approves your solar installation the system will be powered on and you will start saving money! 

They will inspect the following:

Mounting racking is safe and secure

Electrical wiring is done correctly

Installation adheres to code

Your local government will send a notice to your electricity provider to be able to switch the system on.
