At SolarAdvice you’ll find several articles about solar collectors, ranging between the ever popular monocrystalline panels to the thin film designs that are typically worked into everyday life. We’ve even covered a few articles on upcoming technology. For example, panels that charge when it rains and the first solar plane to fly around the world. So, this part of the guide is going to focus on some updates regarding collectors for off the grid solar systems.
Panel Options and Comparisons
It’s not uncommon for people to assume solar panels are fundamentally the same thing. So why pay attention to the type of collector you install? Yes, solar collectors are fundamentally the same thing. They capture radiation from the sun, which they feed through an inverter and into your home. There’s no disputing this part. However, the type of collector is still a big deal. For instance, if you want to invest in system that will take you off the grid, you’re going to need several panels for the job. By choosing a quality collector with moderate efficiency (which is also more friendly on the budget), means you’ll need more panels. A high quality collector with greater efficiency will reduce the amount of collectors you need, and probably last a little bit longer.
You have to make some tough choices, because you have to maintain a long-term perspective with off the grid solar systems. Do you have enough space on the roof? Maybe you have more than enough roof space and like the idea of utilizing panels that fit your budget. Of course, if you want to go off the grid then you probably want to go with a reputable company, like Powerz-on or SunScan. Powerz-on is a local company that produces high grade collectors without importing any parts. They offer a wide range of different panels that offer different levels of efficiency and price plans.
What you need to understand is that solar collectors go through different processes. For example, monocrystalline panels use a single solid silicone cell, while a polycrystalline panel melt pieces of silicone together. In other words, the silicone in the monocrystalline panel has a higher level of purity and therefore is slightly more efficient. It also means monocrystalline panels are more expensive.
Then you get what is called evacuated tube collectors, and there are quite a few difference when compared to a typical panel. Tube collectors do exactly the same thing as a panel, but the heat gets stored inside the insulated tubes and they are primarily used for solar geysers. The more tubes a collector has the more heat it can provide. If we do a rough calculation, you’ll need a 20 tube collector for a 200L geyser tank.
Before You Start Buying Off the Grid Solar Systems
Before you start investing in collectors for off the grid solar systems, take a moment to calculate your average energy usage. Once you know how much you are going to need at peak times, you’ll have a much better idea of how many panels will be required. Look to your budget to choose between the different options.
