What should be powered by lithium battery solar storage?
Project of a lithium battery solar storage for autonomous power supply of a country house located on an island where there is no centralized power supply. Moreover, old car battery, to which a 12V LED carrying lamp connect, act as at least some source of energy.
Furthermore, the cottage comes among the trees, so a 300W solar array install in combination with a PWM charge controller to get the maximum possible power generation. And the system assembles at 12V. The inverter is also powered by 12V.
What should be powered by lithium battery solar storage?
- Moreover, Lighting for ~ 220V through an inverter
- LCD TV
- Recharging smartphones, tablets, laptops and other gadgets
- Moreover, Cordless power tools, battery charging
The installation and installation of solar panels in the country
The slope of the roofs of the summer cottage comes under the crowns of trees that prevent the sun’s rays from reaching the panels. Hence, the lithium battery solar storage initially decides to install on a ground structure, in the most open place of the summer cottage.
The client decided to weld the frame for the solar panels himself. Because by the day the solar power plant install, the frame was not yet there, and then the solar panels were installed on a temporary wooden frame.
How solar panels work?
A popular way to obtain alternative energy is the installation and operation of solar power plants. The systems consist of solar panels, converters, accumulators and some other elements.
The main task of such a kit is to obtain solar energy, transform it into electric current, accumulate electricity and, if necessary, give it to the point of intake – an outlet, a switch.
And although all the components of the lithium battery solar storage are extremely important, most consumers who remember well the physics lessons from the school curriculum understand how each element works. How does a solar cell work?
This question is of interest to many consumers who intend to install panels on the roof or on special tables on the ground. In the entire system, it is probably this constructive link that remains less clear for most users.
Interesting information about lithium battery solar storage
Silicon wafers, unfortunately for inventors, strongly reflect light. Accordingly, part of the solar energy reflects and does not use by the module.
To reduce losses, the photovoltaic plates coat with an anti-reflective layer. And in order to prevent damage to the silicon plate from wind, rain, hail, the module close from above with impact-resistant glass.
At the same time, the operation of lithium battery solar storage by itself will not give any result if the unit does not connect to the following additional components:
Its role is cumulative. Moreover, the battery stores the energy received and converted by the photocells. Installing a battery allows you to use electricity when there is a need for it. The battery provides the building or equipment with electricity at night and in cloudy weather, if there is not enough energy from PV modules.
You need to understand that in the battery, the charge goes with a constant current of high amperage and low voltage. To convert such a current into an alternating current of 200 volts, special devices need.
Charge controller of lithium battery solar storage
It is critical to ensure the correct load and voltage to charge the battery. Charge controllers often find in hybrid inverters or lithium-ion battery packs. These are BMS controllers.
Lithium battery solar storage is responsible for maintaining optimal voltage performance in the network.
So, without any of the listed elements, the system will not be able to work. And for it not only to work, but to demonstrate reliability and stability, the components must be correctly selected.
Their characteristics must correspond to the general calculations. Therefore, the design of the system must trust by professionals working in this field.
Which materials we use in solar panels?
Polycrystalline solar cells produce by melting silicon raw materials and gradually cooling them. The degree of silicon purification in them is lower. The production process is simpler than in the first case. But the result that can obtain with the use of such photocells is not so high. The efficiency reaches only 15%.
So, photovoltaic cells of the selected type in the required number connect in series-parallel. Moreover, this connection principle allows obtaining high voltage and current values. In addition, if one element fails, the circuit remains operational and the panel can function without failure.
Interesting to know:
These are the most popular options and most commonly use in the lithium battery solar storage industry. But scientists, dissatisfied with the complexity of growing crystals and insufficiently high efficiency, continue to look for an alternative to them.
The thin film is elastic, durable, can apply to surfaces with irregular geometry. And, as tests show, film photovoltaic cells absorb rays better in cloudy weather. When it comes to small amounts of alternative energy needed, this option can consider.
- Crystals of solar cells: types and differences
- Moreover, it has already mention that solar panel plates.
What is the difference?
Se solar cells make from silicon wafers, which, in turn, are the thinnest sections of a silicon crystal grown from purified raw materials. They demonstrate high efficiency up to 22%. The first photo modules in laboratories were made of selenium.
This gave an efficiency of about 1 % !!! This is the way from a laboratory to an efficient technology PV modules have passed in almost half a century. Panels with elements are quite expensive, which explain by the high cost of the production process.
