Resource Guide to DIY Solar Panels

Have you been considering DIY solar panels to power your home? More homeowners are beginning to give serious thought to installing solar panels on their home to help the environment and to reduce utility costs. DIY solar can be a great option for a homeowner looking to increase those savings even more by using DIY solar panels to cut out the middleman. Learning how to build a solar panel isn’t easy, but for those with some construction and electrical skills, it can be a rewarding challenge that will save a lot of money on powering your home in the future. This resource guide will walk you through the process of getting started with DIY solar power and includes information on how to make a solar panel, the best DIY solar kits on the market, and even how to DIY a solar generator.

According to a Pew Research survey, here are the main reasons homeowners are considering solar at home:

  • 96% to save money on utility bills
  • 85% to help the environment
  • 67% to get a solar investment tax credit
  • 60% because it would be better for their own/their family’s health

Not only can solar power save you money, but it can also boost your home’s value by up to 4.1%. Some states are requiring that all new homes have solar panels on their roofs, while others offer very high solar premiums, leading to a demand for homes with solar panels. Explore the sites below to see how much DIY solar panels could help you save on your home.

  • Database of State Incentives for Renewables & Efficiency(DSIRE) — This comprehensive list of solar policies and incentives by state has each state color-coded according to the number of programs it has. California, Michigan, Texas, and New York have the most policies and incentives in the country.
  • Renewable Energy Tax Credits — Apply for renewable energy tax credits through the Energy Star program, which offers credits to those with solar energy systems on their existing homes or new construction.

How to Build a Solar Panel

You’ve done the research on the benefits of solar power and looked into the cost savings that making solar panels can provide, and the time has come to put your plans into action. But now, you’re wondering how to build your own solar panels so that they will be able to efficiently power your home or off-grid project. We’ve found some great resources to use when you begin the challenge of building solar panels.

First, you’ll need to decide which type of solar power system you are going to make your own solar panels for. What are you trying to achieve with DIY solar power? Saving money, going off-grid, or using solar for backup power can all require their own specific solar power systems. While all of these systems are made from similar components, their differences can drastically affect the cost and complexity of the project.

  • Grid-connected solar power systems are tied to the electrical grid and can work without a backup battery. This is the most common type of solar panel system used and requires less equipment, which makes this the least expensive solar power option, although its downfall is the lack of backup power.
  • Off-grid solar power systems operate independently of the electrical grid. This type of solar system requires many solar panels and a large battery to maintain constant power for the home, even when the weather is overcast, leading it to be the most expensive option for a solar power system.
  • Hybrid solar power systems are connected to the electrical grid but also have a backup battery system that can be used to store power, making them more reliable and more expensive than a grid-connected system.

Next, you’ll need to look into the solar rules and regulations where you live. They can vary greatly depending on which state or even local jurisdiction you’re located in. Some states do not allow solar systems to be connected to the grid unless the installation was done by a licensed professional.

  • National Solar Licensing Database — The IREC has compiled each state’s licensing requirements for solar installations and continually updates them to remain current.

The next step in the process to build your own solar panels is to design the appropriate solar system for your setup. Below are some tools and sites that can be beneficial in the designing process.
