★★★How to BUILD SOLAR PANELS and SAVE 1000s Dollars★★★
——————————————————————————————————
On the market solar cells can be divided into several classes: – Low-power (of a watt) solar panels used to charge cell phones, PDAs and other similar electronics. They are characterized by the small area of photographic plates and the relatively high price. It’s more of a toy for fans of the exotic.
- Universal solar cells made for powering a wide range of customers in the field. Imported differ very good workmanship and design, the presence of additional adapters, often an acceptable price. Domestic can be both prefabricated and poluseriynye. The price and quality can vary quite widely. If you’re getting to be considered each option separately. This class of solar cells is often the most suitable for tourists.
- The solar cells. Usually a set of plates, attached to the substrate. In fact, they are blank to build a more “advanced” and easy for the end user devices based on them. Type3 Solar most common in the CIS are solar batteries BSC-1, BSC-2, Electronics MCH / 1. These batteries are produced or previously produced many radio-electronic factories. Sometimes there are also commercially imported, mostly Chinese and Korean, solar panels, with parameters comparable to the types of batteries BSC-1, BSC-2, Electronics MCH / 1.
These solar panels can provide a battery charging current in the range of 35-50 mA, not more. And it will be in good sunlight. Therefore, using common solar can provide low-power battery charge capacity with no more than 0.45 A / h Note that batteries are widely used NDEF-0, 45 just have the capacity …
Also note that in the middle of summer, in July, the light period, which gives energy efficient battery usually lasts no more than 7-9 hours. The most effective time for solar panel from 10 to 17 hours. After this time, the current solar cells decreases. Drop the current generated solar panels on cloudy days. Some solar orientation relative to the position of the sun, helps to increase the current generated by them, but … Try to twist the battery in search of better lighting, and make sure that it is not easy.
This is a short documentation of an installation we did at Esther School, Zambia.
The system comprises a 3kW Bi-directional inverter, 12x 250W Poly Panels, 100A MPPT Charge controller and a Battery Monitor System.
