While they do come at a higher price, microinverters can significantly improve the performance of your photovoltaic (PV) modules. They’re best for panels that often experience shade.

Hybrid Inverters: These inverters are usually more expensive and are used in systems that incorporate battery storage.

Mounting Systems for Solar Modules

Roof Mounts: Depending on the roof's shape and condition, specialized mounting equipment might be necessary, impacting the cost for solar panels. Additionally, if the roofing is unsuitable, there might be some additional work that has to be done to reinforce the area.

Ground Mounts: If the roof isn't suitable at all, ground mounts may be an option, potentially affecting the cost of solar panels differently.

Tracking Mounts: These allow panels to follow the sun, improving efficiency but adding to the cost of a solar panel.

The general idea here is that more complex installations require more advanced mounting systems which increases the overall cost of solar panels system.

Balance of System Components and Storage

Wiring and Connectors: High-quality wiring ensures efficient and safe energy transmission and can add to the overall cost of solar panels.

Batteries: If you plan to store energy, the type and capacity of batteries will significantly influence the overall cost of a solar panel system. A large power bank can have the same price as the entire system altogether, but the good news is there are several states that offer incentives for solar systems with storage.

Installation Labor and Other

Labor Costs: This includes the price for the work of skilled technicians who mount and configure the system. It is set by the company that performs the installation.

Permit Fees: Depending on local regulations, there can be various fees and permits required, adding to the solar panels cost.

Inspection Costs: Most localities require inspections, which can further affect the price of a solar panel installation.

Ways to Reduce the Overall Cost of Solar Panels

Solar prices can be substantial, but there are several ways to reduce the cost of solar panels for your home. Here's a look at how you can save on your solar system:

Investment Tax Credit (ITC)

Currently at 30%, the Investment Tax Credit is a significant incentive for solar. This federal credit allows you to deduct 30% of the cost of a solar panel system from your federal taxes. By taking advantage of the ITC, you can significantly reduce the solar panels cost.

Net Metering for Solar Systems

Net Metering is a practice that allows you to sell excess solar energy back to the grid. By connecting your solar system to the local energy grid, you can offset the cost of solar panels through credits on your electricity bill potentially having “free” energy both during the day and night.

Leasing and Power Purchase Agreements (PPAs)

If the solar panel price is a concern, you can explore options like leasing or Power Purchase Agreements (PPAs). These arrangements let you host a solar system without owning it, eliminating the cost solar panels home. In this kind of agreement, you are still able to take advantage of clean electricity for your home at a set rate which is usually lower than the average electricity rate in the region. The downside is you do not actually own the system.

DIY Home Solar Installations: Is the Lower Price Worth it?

For more experienced homeowners, DIY installations can lower the cost for a solar panel by removing labor costs. However, keep in mind that most incentives require your system to be installed by a certified PV provider, so the DIY approach might limit your ability to take advantage of certain price reductions. Additionally, most manufacturers void their warranties if the equipment is not installed by a professional so that might be another big disadvantage of this approach. Make sure to weigh the pros and cons to make a decision that will benefit you financially both short term and in the long run.
