A Photovoltaic (PV) module is the main component for Solar Energy Systems that does the job of converting sunlight into electricity. Today it is not limited to crystalline silicon cells, but now available are several new models of PV solar panels for sale across Ireland. So while it is a great decision to endorse solar energy in your household, you need a careful selection of the equipment that will ensure you get the best outcome and maximum energy savings. Here are ideas about the things to consider when buying new solar panels for your house.
Types Of Solar Panels For House Installation
Photovoltaic Solar panels are comprised of multiple solar cells that are semiconducting materials capable of harnessing sunlight and produce Direct Current (DC). There are basically 3 types of solar panels to choose from, based on the technology of construction and material. These three types include:
Multicrystalline or Polycrystalline cells - low-cost, low-efficiency, perfect for small homes and couples.
Monocrystalline cells - high-efficiency, high-aesthetic value, higher cost perfect for family homes with multiple appliances and electronics
Thin Film cells - portable and lightweight, moderate cost, perfect for large families and commercial use, but low in energy efficiency
While both polycrystalline and monocrystalline panels are made of silicon, the main difference between the technologies is the alignment of the cells - while monocrystalline panels have a single crystal construction, the polycrystalline PV panels have multiple fragments of silicone melted and placed together. You can easily tell apart the two wherein Polycrystalline Panels have a blue colour, while Monocrystalline panes are available in pitch black, which makes up for a better aesthetic value. In Ireland, there is higher availability of both the variants of PV solar panels for sale in the domestic domain.
Thin-film panels are second-generation technologies that are constructed using layer by layer deposits of thin-film of photovoltaic and place them on a substrate material such as plastic, metal or glass. This is the predecessor of the Third-Generation of relatively high-efficiency solar technology, that have higher conversion capacity and comparatively lower cost. These are more common in the commercial domain.
Types Of Installation for Domestic Solar PV System
So having solar panels is not the last thing, you also need to know which is the best installation process suitable for your home. Ideally, for home use, the following options are most common:
1. Solar panel roof-mounted systems
2. Ground-mounted systems
There are also less conventional options of having window-mounted cells or using brackets at the exterior of your building if you don’t have a roof. Roof-mounted PV systems are comparatively cheaper than other options.
Things To Consider Before Getting Residential Photovoltaic Solar Panels
There are altogether 7things to consider before getting new solar PV panels for your house
1. Budget - Cheap is better than expensive, but efficiency is more worthwhile than low efficiency, but low efficiency can be sufficient for single-person use with small requirements.
2. Size - It is all but a single equation if you have a small house and limited needs get small solar panels, as you need more, buy more panels and to the existing grid.
3. Legal Liabilities - Now that it has become a legal obligation to have renewable energy systems if yours is a new house, then the most cost-effective and hassle-free renewable energy system for a house is a Solar PV system.
4. Grants - Choose your installer wisely. Renewable Electric Ireland solar PV grants and incentives are offered by SEAL and many other authoritative bodies, and your installer can get you closer to getting this grant. So a good thing to have a SEAL registered installer.
5. Permissions - Residential solar PV systems are exempt from the Planning Permission in Ireland or any other permits. This applies to both roof mount and ground mount systems that fall under the area limit of 12 square metres. Moreover, there is a rule to follow that your panels must be at least 50cm away from the edge of the roof.
6. Insurance - Make sure that your installer has insurance so that if there is any damage to your solar panels during installation, they can compensate you. Similarly, public liability insurance is also essential to make sure they are safe at work. But the onus is on you if you are at fault for any damages caused to the installer’s equipment or they are physically hurt. Your homeowner’s insurance can cover that.
7. Warranty - You don’t get PV solar panels for sale in Ireland without the warranty papers. You can have a long-term warranty of an average of 20years. Always have the warranty certificate.
