Tips For Choosing Solar Panels

Considering using solar power as a method of greening your life and lightening your environmental footprint? When choosing panels for your solar power system, there are a variety of factors worth considering.


The cost of a photovoltaic panel is identified in part by the size (in Watts), the physical size, the brand, the toughness/ durability (or guarantee period) and any accreditations the solar panel might have. Picking a solar panel on price alone is not sensible, as it may not fit the location you wish to install it, may not have the needed accreditations to receive federal government refunds, or may not have actually the warranty needed for economic repayment of the power produced.

Sturdiness/ Longevity/ Warranty

The sturdiness or durability of a photovoltaic panel is necessary for a number of factors. To start with, if the photovoltaic panel just has a Ten Years guarantee and it is utilized in a grid link system you would anticipate the photovoltaic panel to produce sufficient power to spend for itself within 10 years.

Likewise, if the panel is to be used in a critical system you shouldn’t risk installing photovoltaic panels that aren’t as robust as the others. Respectable photovoltaic panels will have service warranty a duration of 25 years.

Photovoltaic Panel Size and Wattage

The size of the photovoltaic panel in Watts will straight impact the cost, as solar panels are normally priced (and compared) in dollars per Watt.

Watts are related to the output of each panel; meaning a 100 Watt panel under perfect conditions will create 100 Watts of electricity each hour and a 200 Watt panel will create 200 Watts each hour. Therefore anticipate to pay double rate for the 200 Watt panel, compared with the 100 Watt panel.

The output of a panel also impacts the physical size of the panel, implying the 200Watt panel will be bigger in size to the 100 Watt panel.

The type of solar batteries utilized in its production likewise determines the size of the solar panel. They crucial problem to consider is that your system total has enough watts to power your appliances, which the solar panels will fit in the area you wish to install them.

Photovoltaic Panel Efficiency

There’s much dispute about efficiency in solar panels, i.e. how reliable the panel remains in converting sunlight to electricity; but the crucial point to bear in mind is that a 100 watt photovoltaic panel will produce 100 watts; no matter its performance rankings.

Solar Cell Type

Mono-crystalline silicon – The most effective and produces the smallest solar batteries, and therefore the tiniest panels.

Poly-crystalline (or multi-crystalline) silicon – Produces the next most effective type of cells, however comparable wattage panels are bigger than their monocrystalline counterparts

Amorphous (or thin-film) silicon – Uses the least amount of silicon as well as produces the least effective solar cells. This means thin movie system use up more location than the other 2, however it has the benefit of providing versatile panels that can be utilized on curved or irregular surfaces not suited to strong panels.

Solar Panel Suitability

Mono-crystalline and multi-crystalline work effectively in brilliant cool conditions, whereas amorphous (thin-film) silicon will be more efficient at higher temperatures.

We normally suggest monocrystalline or multi-crystalline for large unshaded roofings, and amorphous panels for roofings with partial shading.
