It is well known to many entrepreneurs that an investment in solar panels is very interesting. An investment in solar panels can easily yield a 7 percent return. With an SDE++ subsidy, up to 15 years. Suppose you have decided to start earning with a solar panel installation, what should you pay attention to when you work with a solar panel provider?
While searching for new agricultural equipment, you will soon discover that the prices of a John Deere, New Holland or Fendt can vary considerably. As an agricultural entrepreneur it is not easy to make a choice between the overwhelming number of models, series and brands. Ultimately, you want to make a choice for quality.
The same applies to the purchase of a solar panel installation. You request quotes from a number of parties and the different providers come up with different prices, products and quality levels. Sometimes you can't see the forest for the trees. A solar panel installation consists of various parts that must be able to work together well: the panel, the cabling and the inverter. How do you rate the quality of this?
The panel
In order to properly assess the quality of a panel, the following points are important: the generating capacity, the power guarantee and the panel's resistance to the conditions on an agricultural farm.
Nowadays a good quality panel produces a power of 370 WP (Watt peak). A manufacturer that believes in its own product will dare to issue a performance guarantee of at least 25 years. This means that solar panels will yield a high percentage (minimum 80%) of the original yield in that time frame. Panels placed on the roof of an agricultural company must be able to withstand conditions such as dust, sand, moisture and ammonia. A quality panel meets these requirements.
Inverter
The cabling runs from the roof to the inverter. An inverter ensures that generated power (= direct current) is converted into alternating current that is suitable for the energy grid.
The way in which the solar panels are connected to each other - and to the inverter - influences the generating capacity of an installation. This can be connected in series or by means of 'power optimizers' in pairs.
A traditional series connection works like an old Christmas light garland: if 1 of the lights works less or not at all, the yield of the entire garland suffers. In the case of a solar panel installation, this can be due to circumstances such as falling leaves on the panels, dirt, shade, temperature differences, etc. An installation that is connected in series will yield less than an installation that is connected per 1 or 2 panels by means of power optimizers. switched. If you opt for power optimizers, you opt for more generated energy and therefore more efficiency. It should be added that with an installation with power optimizers you also opt for safety: the installation is touch-safe and equipped with an electric arc detection to prevent fire.
Mounting system
Solar panels should of course never blow off the roof. A high-quality mounting system is vital. Also make sure that certified double-insulated cabling is used and a cable duct in which it is neatly stored. A good quality installation is an installation that is safe. earlier we already wrote that the knowledge and skills of the installer influence the return. Choose a party that scope 12 let it be approved. This ensures a safe installation, a low fire risk and an optimal return.
