Introduction: Understanding Solar Power
Solar power is an excellent resource for homestead owners who want to take an active role in their energy needs. It’s a renewable and clean source of energy that can help reduce your reliance on traditional electricity sources, like coal or natural gas. This guide will provide homesteaders with the tools they need to understand solar power and how it works, and then present some of the options available for DIY solar power projects.
Benefits of Solar Power
Solar power is gaining in popularity due to its environmental benefits and economic advantages. It’s clean, renewable energy that doesn’t produce air pollutants or other greenhouse gases like traditional energy sources do. Additionally, it can reduce your reliance on grid electricity and help you save money on your energy bills. Or will it?
DIY Solar Power Projects
DIY solar projects are a great way for homesteaders to become more self-sufficient and reduce their reliance on grid electricity. With the right tools and materials, anyone can create a solar power system that can provide enough energy to meet their home’s needs. Many different projects can be undertaken, from small solar setups to more complex systems.
Types of DIY Solar Projects
There are a variety of solar power projects for homesteaders who want to create their own energy solutions. These range from simple, inexpensive solar water heaters made from recycled materials, to more advanced and expensive photovoltaic (PV) systems. Solar water pumps and solar lighting are popular for providing energy to livestock, while off-grid power systems can be used for homes.
Components of a Solar Power System
- A. Solar Panels: These are the most visible part of a solar power system, and they collect energy from the sun to generate electricity. They come in a variety of sizes and wattages depending on your needs.
- B. Charge Controller: This device is used to protect your batteries from overcharging or discharging too quickly, and it’s essential for any solar power system.
- C. Inverter and Battery: The inverter converts the DC current created by your solar panels into AC current that can be used in your home or business. Now about batteries. There are tow main types of batteries
Batteries for Solar Systems
Batteries differ significantly in their energy storage, release methods, maintenance requirements and life span.
- Deep-Cycle Batteries: These are specifically designed for continuous use and repeated draining and recharging, known as deep cycling. They provide a steady amount of current over a long period, making them ideal for solar power systems that require a consistent energy supply. Unlike ordinary batteries, they can be deeply discharged using most of their capacity. These are used in recreational vehicles like boats and are popular for off-grid applications.
- Lead-Acid Batteries: Traditional lead-acid batteries, on the other hand, are designed for short, high-power bursts of energy, such as starting an engine. They do not tolerate deep discharge well; doing so can severely shorten their lifespan. Thus, they are not ideal for solar power systems where energy needs to be stored and used over extended periods. These are much like your car batteries. This is the cheapest option but it also lasts the shortest amount of time.
- Lithium Ion Batteries: The newest type of battery specifically designed for solar power systems is the lithium-ion battery, which provides superior energy storage with low maintenance. Its ability to handle deep discharges and provide a steady supply of current makes it an excellent choice for anyone looking to install a solar power system.
- Flow Batteries: Flow batteries use tanks of liquid electrolytes to store energy. They can be discharged and recharged with very little degradation, making them an attractive option for those who need large-scale storage capabilities. Considered by many to be the best battery for solar energy, they are also very expensive.
When deciding what type of battery is right for your solar power system, there are a few key factors to keep in mind. Consider how much current you need, how often it needs to be discharged and recharged, and how much maintenance you’re willing to perform
Planning Your Solar Power System
Before you start building your solar power system, it’s important to do some research and plan out what components you need. Start by determining the amount of energy you want your system to generate, then calculate the wattage of the solar panels needed to produce this amount of power. You should also take into account how much room you have available for mounting the system.
Use a calculator to determine your kwh usage and then your solar array size needs based on how much electrical usage you want to replace with solar. Sun Watts will show you systems and cost in that size. This is just for the system not installation and without battery storage, just grid tie.

Cost of Solar
For my 1500 square foot house in an area with 6 hours of average sun to replace 100% of my electricity I need about a 9 kW solar array, An array this size ranges from 12 to 20 thousand dollars for just the kit. My electricity bill runs about 150.00/month which will probably go up as it has been doing. To pay for itself my system if I install it myself would take 6.6 years to pay for itself. Keep in mind this cost does not include battery storage which would be another 13,000 or so. To have it installed you can add another 10,000 to the cost and you are looking at more than 20 years to pay for itself.
If you have come this far, next, calculate the size and number of batteries you need for your solar power system to ensure you have enough energy storage capacity to meet your needs. Additionally, make sure the type of battery you choose is compatible with your charge controller and inverter. Last but not least, determine what type of mounting system will best suit your needs so that it can securely hold your solar panels in place. Generally, a south-facing roof is used.
By taking all of these factors into account, you can ensure that your solar power system is properly designed to meet your energy needs and maximize the efficiency of your renewable energy system. With careful planning and research, you’ll be able to enjoy the benefits of clean, green energy for years to come! But it won’t be cheap which is why doing as much of it yourself as you are comfortable you can do safely is something to at least consider.
Tax Credits
You can get tax credits to offset the cost of a solar system and you can find infrmation about that here.
From what I can see thats only helpful if you already have the income to afford 20,000 dollars or more for a system. If you can, I would defintely look into the tax credit.
Installation of Solar Systems
Installation of a solar power system is a multi-step process that starts with the assembly of panels. Secure individual solar cells together to form a panel, taking care to align them properly for maximum sunlight exposure. These panels are then interconnected to form an array.
After the assembly of panels, the next step is setting up the batteries. Choose a well-ventilated, safe location for your battery bank. Connect the batteries in a series or parallel arrangement, depending on your energy storage requirements. Ensure all connections are tightened and insulated properly to avoid any power leakage.
The third step involves installing the inverter. This critical component converts the DC power produced by your solar panels into usable AC power. The inverter should be installed in a protected, ventilated area, close to the battery bank.
Once the inverter is in place, the next step is connecting the system to your house. This involves running electrical cables from your solar array and battery bank to your home’s main electrical panel. It’s important to include a circuit breaker in the system for safety purposes.
Remember, each of these steps requires careful planning and adherence to safety guidelines. Depending on the complexity of your system and your comfort level with electrical work, you might want to consider hiring a professional installer to ensure everything is set up properly and safely or at least an electrician to be sure you hook up everything correctly.
V. Maintenance and Troubleshooting
Once your system is up and running, you’ll need to make sure that it stays in good working order. Regular maintenance will help ensure the efficiency of your solar panels as well as the safety of your family.
You should inspect the system at least once a month for any loose or damaged wires, connections or cables. Make sure all surfaces are clean and free of any debris and dirt. If you notice any unusual activity or changes in performance, it’s best to call a professional installer who can assess the issue and take care of the problem.
Troubleshooting solar systems can be tricky, so make sure you have all the necessary tools like a multimeter and electrician’s tape ready at hand before attempting any repair work. Familiarize yourself with the manual so that you can spot and resolve any issues quickly and efficiently. That way, you can rest assured that your solar system will continue to operate without any issues for years to come.
Finally, you’ll need to factor in the cost of insurance. Solar panels can be expensive and therefore you must be adequately covered in case of any accidents or damages that may occur. You might also consider insurance might be difficult if you self-install so getting an electrician to sign off might be a good idea.
No matter what type of solar system you choose, it’s important to remember that regular maintenance and inspection are key factors in ensuring that your system continues to perform optimally. With the right approach and care, you’ll be able to enjoy all the benefits of solar energy without any hassle.
Conclusion
Looking at the above information, I am not seeing a total house solar system complete with battery storage and installation in my future. What may be possible for my pocketbook is solar system to run my well-pump perhaps and the electricity going to my shed. This could decrease my electricity use, and ensure I have water in a power outage and not break my bank in the process. Also, both the well and shed are far enough away from my house if I catch something on fire the house will be safe since the only way I can afford even that is to do it myself! The well has such variable power draw it may not be a good fit for solar. I’ll let you know how it works out!
I invested in this course to teach myself about solar since thats the only ways I will ever be able to afford it! So far it’s been a good resource.
