![]() ![]() Off-grid solar systems use deep cycle batteries, which are designed to be discharged and recharged gradually. You can draw power from your battery bank to run your appliances at any time. The centerpiece of off-grid solar systems. In terms of performance, mono and poly solar panels will produce power equally well, but an array of poly panels would take up more room on your property. Mono solar panels cost a bit more than poly panels, because their increased efficiency allows you to fit more solar in a smaller space. They are slightly more efficient than polycrystalline (poly) solar panels, which contain cells made of blended fragments of silicon. Monocrystalline (mono) solar panels are cut from a single section of silicon. The difference is that 120-cell panels utilize half-cut cells, which are slightly more efficient and resistant to failure.ħ2-cell and 144-cell solar panels are about 3.5 feet by 6.5 feet, with 144-cell panels using half-cut cells as well.Ħ0/120-cell panels are easier to carry and offer more flexible design options, while 72/144-cell panels cost less to install. Common solar panel sizes:īoth 60-cell and 120-cell solar panels are about 3.5 feet by 5.5 feet. Any traditional 60/120 or 72/144 cell solar panel will work just fine, and if you have space on your property to mount full-sized panels, that will be your most cost-effective option. Now, MPPT charge controllers allow us to make use of standard, mass-produced solar panels in off-grid applications. Nowadays when a panel is marketed as "off-grid" it often means that the wattage is lower than the current standard, and many of the panels marketed this way tend to be of inferior quality. ![]() There used to be panels that were designed to match the lower voltages of specific types of charge controllers and battery banks, but the technology has improved enough that the design standard has become outdated. While you may find that some panels are marketed as “off-grid solar panels,” this is a bit of a misnomer. Solar panels absorb the sun’s rays, converting sunlight into DC (direct current) power. For example, most grid-tie inverters are not configured to connect to a battery bank. It’s important to pick components specifically rated for off-grid use. Here’s a quick overview of the parts you can expect to find in your off-grid solar system. ![]()
