Solar Panel Buying Guide: What to Know About Solar Panels

Aug 21


This guide will help you buy solar panels. If you are interested in solar panels for your home, start here.

It is a big decision to decide whether or not to install solar panels at home. The question of whether the cost savings and energy efficiency will be worth it is another important decision. It's possible to wonder if you should replace your roof or how long the solar panels will last. There are many things to take into consideration before purchasing home solar panels. We'll explain the basics of solar panels, and answer any questions you might have so you can make an informed decision about which panel is right for your home and budget.

Best Solar Companies

Many businesses are experts in solar panel installation. Look online to find solar panel suppliers and installers near you. You should know the qualities to be consider when hiring solar company

SaveOnEnergy allows you to search, compare and sign up for the best energy deal for your home. Answer a few questions to receive a price quote from our solar experts if you are interested in solar.

The arrays can be installed by a professional or manually if you have the skills. You can choose the option that is most comfortable for you with solar installation. If professional installation is what you want, talk to your solar panel supplier. Some suppliers provide special pricing or can recommend a subcontractor who can install it for you.

How do solar panels work 

A solar panel, also known as a module, is composed of a layer made of silicon cells, a frame of metal, a glass case unit, and wiring that transfers electric current from the silicon. Silicon (atomic #14 in the periodic table), is a nonmetal that has conductive properties. It can absorb sunlight and convert it into usable electricity. A silicon cell is activated by light when it is exposed to light. This causes electrons in the silicon cells to move and create an electric current. This phenomenon is called the "photovoltaic effects" and describes the functionality of solar panel tech.

This photovoltaic effect is the basis of solar panel technology. This photovoltaic effect was discovered for the first time in 1839 by Edmond Becquerel. It is a property of certain materials (known as semiconductors), that allows them to create an electric current when exposed to sunlight.

These are the main steps of the photovoltaic (or PV) process:

The silicon photovoltaic cell absorbs the sun's radiation The sun's rays interact with the silicon cell and electrons start to move. This creates an electric current.

The wires collect and feed the direct current (DC), electricity to a solar converter to convert it to alternating current electricity (AC).


Solar Panels Benefits 

Why would you choose home solar panels? There are many benefits to installing solar panels in your home:

  • Energy savings: This is the most obvious benefit. You can power your home without the need for an electrical grid. This will help you save money and, if you can generate more power, you may be eligible for credit on your electric utility bill.
  • The abundance of solar power is impressive: According to the US Department of Energy, only one hour of the summer sun can meet the annual US electricity consumption. You can still save electricity even if there is a lot of shade or rain.
  • Solar panels can increase the value of your home.
  • Going green: Solar is a renewable resource that can be used to reduce your carbon footprint.
  • Independence from electric grid failures Your own solar power can help keep the lights on if you have frequent power outages.
  • You can power your camping with small solar panels. These are easy to mount on RVs and you can also take them camping.

Solar Panel Installation

Each state or municipality has its own rules and regulations regarding solar panels. For more information, we provide a detailed guide on solar panel installation.

It depends on what you need, approval may take some time. This is why it's important to get everything in order before you begin browsing for solar panels. Good installation companies will take care of the permitting process. But be sure to inquire about them.

Solar energy costs

Solar panels have seen a significant drop in cost due to increased efficiency. Over the last decade, the cost of a solar panel installation has dropped by over 60%. Many industry experts expect that this trend will continue in the future.

Depending on your location, there may be rebates or incentives that help to lower the cost for solar energy. Nationally, the federal Investment Tax Credit is one of many incentives for those interested in solar energy. It allows you to deduct 26 percent of the cost to install a solar array system. This incentive will not last forever. In 2023, it drops to 22% and is then eliminated completely for residential solar installation in 2024.

Many states and utilities offer additional incentives (such as net Metering) in conjunction with the federal ITC. This helps to lower the cost for solar power.
