Purchasing solar panels can get rid of or substantially reduce costs of home energy because the panels help in absorbing light and generating energy. But buying the right solar panel and its mounting system is a challenge for many.
The key is not to be carried away by advertisement and focus on important aspects because it is a substantial investment. The following are tips to consider while buying a solar panel:
Ask colleagues, neighbours, friends and family who have had experience of installing solar panel systems. They can share details of their experience and alert you to any problems, which you can avoid.
Consider the details of warranty offered by manufacturers. In case it has a long warranty period (like 20 years) and the company is well reputed, you can expect the panel to last long and make a profit for you. But for honoring of a warrantee, the manufacturer must continue operating so for Brisbane solar panels choose companies who have a track record in Australia.
- Be realistic about price expectations
If you are paying much less than that quoted by other solar panel companies, you may be stuck with poor installation or low quality equipment. Equipment of good quality does not come cheap and like most items, you will get what you paid for. You must compare warranty periods and components provided by the company. Big, long established companies can pass on cost savings due to high buying power but other companies will have to cut corners to offer low prices.
This factor applies to all solar panel companies but particularly to purchases which feature rebates offered by the govt. Certifications of solar panels reveal the type of testing which has been carried out on them. For example, TUV IEC 61215 indicates that solar panels have been subject to tests by an independent laboratory and meet their professed standards. But self-certification must be taken with a pinch of salt.
- Decide on kinds of panels
Typically, if you have limited space, it would be ideal to buy expensive and super-efficient mono-crystalline solar panels. But this trend is changing with advances made in polycrystalline panel technology.
Polycrystalline panels work best in conditions of dull weather, have long lifespan and are less expensive. But they are less effective and larger than other solar panels. monocrystalline panels work properly in bright sunshine, are smaller than polycrystalline panels and very efficient. But they are more expensive than other panels and more fragile.
Consumers can consider the nature of options and make an informed purchase.
- Consider space and location
One must consider the amount of space reserved for panel. In small areas receiving lots of sunshine, monocrystalline panels are suitable. In areas with low light and more space, polycrystalline panels are a better option, gathering light from all angles for maximum efficiency.
Also space meant for panel installation must be free of hindrances like shadow of other large buildings or over hanging trees.
Ensure that mounting system is engineer certified for the region where you reside. For example, in areas prone to cyclones, the mounting brackets and mounting system must also be cyclone rated. Mounting system is a crucial component but some suppliers ignore this factor.
These are some tips for buying and using a solar panel.
