Guidelines for Choosing the Best Off-grid Solar System

Like any other complex system, how well an off-grid solar system works depends on the individual parts. So, choosing the best system requires researching the different components. This might seem intimidating, but there are core components of the system with which you can start. Even if these are the only options you weigh, you can easily maximize solar production and storage.

 

Consider your off-grid solar system budget

 

The best solar system for you is the one you can comfortably afford. It doesn’t mean loans are off the table, but it does mean you should take a good look at how much you can spend on solar without stretching your budget too thin. While you can recoup your investment, it generally takes several years. Consequently, it’s important to plan your initial investment carefully.

Calculate your off-grid solar system energy needs

 

Check your energy usage over the past year to determine your monthly, annual, and seasonal energy usage. Divide your annual total by 12 to determine how much you need to replace. This represents your average monthly power consumption. You also need to determine peak power usage. Check the wattage of all your high-consumption appliances and the appliances you run concurrently. This will tell you how big your inverter and solar array need to be. Finally, tweak your numbers by determining what you can replace to lower energy usage. Appliances become more energy efficient every year, so consider upgrading. The 12-volt appliances used in RVs are expensive, but they’re well worth the investment.

 

Purchase solar panels you need

 

When looking at solar panels for your off-grid solar system, you may have noticed you could save money by buying polycrystalline panels. These blue panels are less effective than monocrystalline panels but cost significantly less. Constructed with high-performance monocrystalline solar cells, Xinpuguang@-rigid series solar panels have a conversion efficiency of more than 23% under sunny days.

Match your inverter to the solar panels

 

Like generators, your inverter operates on a watt rating. It determines how many watts it can process simultaneously before overloading your off-grid solar system . Most people agree that bigger is better for the inverter, but too big can draw too much power from your system. Why? Because inverters use power to convert DC to AC. Thus, a good rule of thumb is to match your solar panels and your inverter. For example, if you have 10,000 watts of solar panel on your roof, install a 10,000-watt inverter. If you bought a bigger inverter than the solar array and used as much, the solar panels would not keep up, and the battery bank would quickly drain.

 

Choose an MPPT solar charger

 

Like many other technical fields, solar installation has its fair share of jargon and acronyms. The solar charges that feed and protect your battery bank are an excellent example of this. PWM stands for pulse width modulation, and this controller is the cheaper and more readily available of the two. While PWMs are as functional for keeping the batteries safe in your off-grid solar system, they don’t work as fast as MPPT solar chargers. MPPT stands for maximum power point tracking, which takes a more complex route to keep your batteries charged and safe. These chargers do a much better job of varying their own energy usage to maximize input from your solar array. They can also handle voltage variations from your batteries and panels.

 

Install lithium batteries

 

For entirely off-grid living, adequate battery storage is crucial. While several cheaper alternatives to lithium-ion batteries exist, the benefits are well worth the cost.
