A solar cell panel, solar electric panel, photovoltaic (PV) module, or solar panel is an energy-generating assembly of photovoltaic cells mounted in a framework. Solar panels generate direct current electricity by using sunlight as a source of energy. A PV panel is a collection of PV modules, and an array is a system of PV panels. Photovoltaic arrays provide solar electricity to electrical equipment. Solar panels can be a significant investment, but there are ways to make them more affordable. 

Here are a few ways to make solar panels more affordable:

1. Purchase used solar panels: You can find used solar panels for sale online or at your local hardware store. 

2. Increasing the amount of light captured : Improving the efficiency of solar panels is one way to reduce the cost of solar. With higher efficiency, fewer panels or modules are required to meet a given power target. This means fewer workers, less land, and fewer machines.

3. Solar panel grants: There are many government and non-profit organizations that offer solar panel grants. Check with your local government or utility company to see if you qualify. 

4. Solar panel rebates: Some states offer solar panel rebates to encourage homeowners to switch to renewable energy. Check with your state’s energy office to see if rebates are available. 

5. Solar panel financing: You can finance your solar panel purchase through a loan or lease. This can make solar panels more affordable by spreading the cost over time. 

6. Solar panel leasing: You can lease solar panels from a company for a fixed monthly payment. This can make solar panels more affordable than purchasing them outright. 

Making solar panels more affordable is a great way to help the environment and save money on your energy bill. There are a variety of ways to do this, so find the one that best fits your needs.
