Please consult one of our specialists before buying a solar panel for your house or cottage.
How to choose the right solar panel
After installing solar panels on the rooftop of your house or cottage, you will isolate yourself from energy price fluctuations and voltage drops. Once you have paid off your solar panels and their installation, you can forget about the traditional energy sources for at least 25 years.
Types of solar panels for your home
Monocrystalline Panels
They are created from monocrystalline silicon. These panels are very efficient but have higher price per Watt.
Due to their source material properties:
- Energy conversion efficiency is 16-18%
- High efficiency under low light conditions, which is important for power production during fall and winter
Monocrystalline silicon is created in specialized growth vacuum furnaces. Due to its purity of 99.99%, energy efficiency is much higher than of polycrystalline panels. These panels are most appropriate for marine vessels, RVs – or any places with limited installation space.
Polycrystalline Panels
The main advantage of polycrystalline solar panels is their affordable price. In cases when the maximum generation of energy from 1 Watt is not the main goal, installation of affordable solar panels is the best option. Polycrystalline panels are made of large number of crystallites of different sizes and orientation. They are not as efficient as monocrystalline modules, but lately that difference in efficiency is quite small. Affordable solar panels work best for residential houses and large commercial buildings or factories.
Solar panels’ capacity
To understand the number and efficiency of solar panels you need to make your house completely energy independent, there are few factors that you need to consider:
- Amount of power necessary to ensure the work of all appliances in the building (refrigerator, iron, vacuum cleaner, etc.)
- The sun rays intensity
- Geographical location
- DC to AC losses and battery charge/discharge losses
- Losses in the conductors
Let us assume that the electricity consumption of a house is 300 kWh per month. By dividing this value by 30 days and 7 hours of active work of solar panels per day, we get 1.42 kWh. You will always need to add 40% loss on battery and an inverter to the resulting number. This way, to provide a small house with electrical energy in the summer, you will need an array of solar panels with a capacity of 2 kWh. In order to receive enough electricity in spring and autumn, it is better to increase the array by 50%, or by another 1 kWh.
The most popular solar panels among our customers are 300 W solar panels. We offer solar panels ranging from 290 Watt to 360 Watt at the competitive prices.
Popular brands of solar panels
When choosing manufacturers and components for our products, we prefer the newest technological developments. That is why the solar panels and their components we offer are highly efficient.
Panasonic – have 27% higher power density compared to other brands. That allows to generate 19.7% more energy from 1 m2 (11 ft2).
Canadian Solar – are compact, which allows for economical use of roof surface. They are 11% more efficient compared to other common modules. They also have excellent efficiency under low light conditions – up to 97%.
Solar Panel Warranty
The manufacturer’s warranty for solar panels is 25 years. After time, their efficiency is expected to decline to 80% of rated power. For monocrystalline panels “the aging effect” is much slower, which has to do with their uniform structure.
