Battery Reconditioning for Solar Energy Power Systems

Installing solar panels can reduce the carbon footprint of the household with the equivalent of 88 trees planted each year. If you are interested in this innovative technology, we will detail all about it in this, so that at the time you will have to take a decision you have all the information.

Solar panels are made of 2-layer solar cells, joined by a sandwich-like semiconductor element. Silicon cells make it easier to detach the electron of the atom so that it moves freely. When the light hits an atom, it is absorbed by one of the electrons around the particle, stimulating the energy of the particle.

Judging by their use, you can choose between photovoltaic panels and thermal ones. From a construction standpoint, they are divided into monocrystalline, polycrystalline and amorphous for photovoltaic ones or vacuum tubes for thermal ones. You can find more information on this link.

The photovoltaic panels:-

The photovoltaic panels convert solar radiation into electricity, into a photovoltaic system with batteries or connected to the grid. Its photovoltaic cells capture energy as a light detector and turn it into power through a two-layer silver film mounted around a semiconductor layer.

1. Monocrystalline photovoltaic panels are the most quality products, but also the most expensive ones. Technology has evolved from 6% yield from 1950 to 20% today, depending on the size of the solar panel.

2. The most widespread photovoltaic panels are the polycrystalline panels, for a price 10% lower but also with a maximum efficiency of 16%.

3. Amorphous photovoltaic panels remain the least efficient in intense light conditions (5-7% yield) but compensate if they are located in low light conditions when they are the best performing. Another benefit is that they can be mounted on curved or flexible supports. It's usually the choice of carriers to be on boats.

Thermal solar panels:-

Leonardo Da Vinci has been using solar energy for domestic purposes since the fifteenth century when he used a convex mirror to direct the light to heat the water. The solar thermal panels today are built for the same purpose, extended to the warming of the home or pool, in a slightly more developed system than the one of the Renaissance thinker.

The solar photovoltaic system is composed of the inverter, controller, and the battery for solar energy storage. Depending on the manufacturer, solar batteries have warranties between one and two years. However, the most important thing about solar cells is not the guarantee (although it matters), but their life cycle. Due to forced bite withdrawal cycles, their life may last only 2-3 years. You can find below battery tips for your solar systems.

Purchase solar batteries:-

To ensure the storage quality of your solar energy power system, you need to purchase solar batteries first. They have a lifetime depending on a discharge cycle. Solar cells have the advantage of slow discharge, and the number of discharge cycles at C10 (i.e., a constant 10-hour discharge) should be followed.

Example: A solar battery will withstand some 1000 discharge cycles at a maximum discharge of 10%. This means that the solar cell will "live" for 1000 days (about three years) if 10% of its capacity is discharged every day. If a 100 Ah / 12V battery discharges only 10 Ah per day, the lifetime will be three years. In the event of a higher discharge (20%), lifetime is dramatically shortened to one, maximum two years.

Properly dimension the solar cells:-

Another important thing is the correct sizing of the cells. Due to the fact that cells are an essential factor in the final price of the installation, most vendors undersize the battery bank. However, the lower price thus obtained will result in a lifecycle up to 2-3 years.

Be careful, the seller knows he is "covered" by the one-year warranty he offers, so you have a product that after 2-3 years will no longer work. Those who bought the first off-grid systems are already having problems with them.

Even if it is not easy to find a true professional, we recommend that you only talk with certified and experienced specialists in the investment in a photovoltaic system.
