Solar panels have improved greatly over the years and the latest panels are more powerful than ever before. Panels can vary in power measure in watts and total combined power of all the solar panels is the system size calculated in kilowatts KW. For example 22 x 300 watt panels is 6600 watts or 6.6KW.
Panels are available in poly crystalline or mono crystalline, which are the ones with the diamond shape between the cells. Mono crystalline panels work better in low light conditions, so they reach full power earlier in the day, maintain full power later in the day and generate more power on cloudy days and are more expensive and better quality than the poly crystalline panels.
There are many things to consider when choosing a solar panel including the efficiency rating, power output, power drop off over time with the age of the panel affecting the performance, hail repellent qualities of the glass and moisture protection system in the manufacturing process to ensure no moisture getting inside the panel creating mould, which will block the light and render the panel useless.
Tier 1 solar panels is a term used in the solar industry to describe the top tier of solar panels brands, but don't be fooled as there are are 350 panels in the Tier 1 list and many of them are poor quality. In order to get the government rebate solar panels must be in the Tier 1 list. We recommend the top 10 panels on the Tier 1 Bloomberg list which is an independent list, which ensures fantastic quality, performance and reliability.
Most solar panels come with a 25 year performance warranty and a 10 year product warranty, as there are no moving parts in a solar panel the performance warranty is the most important as this guarantees that the panel with produce DC energy (battery power) for a minimum of 25 years.
Split panels are one way you can reduce efficiency loss from shading issues at your property. A split panel is like having 2 solar panels in 1, so if one section of the panel is affected by shade, it does not affect the opposite side of the panel. If you would like to know more about the solar panels please contact one of our solar specialist and we will answer your questions and recommend a solar panel that suits your energy needs and budget.
