Finding one of the best solar installers in New Jersey can be difficult. Some dealers will take advantage of your investment without delivering the highest standard of service in return.
The solar industry is experiencing rapid growth, receiving 33% annual growth, with more people installing solar panels on their properties. It means that competition is high, with reputable dealers struggling to stand out. If you’re planning on installing solar panels, read to learn how to find quality solar panels and installation.
Look at Solar Panel Inverter
The device converts your solar panels’ direct current (DC) electricity into alternating current (AC). Inverters come in different shapes and sizes, so choose one that fits your needs.
To prevent damage to your electronics, look for a power inverter with a high wattage, several outlets, short circuits, high temperatures and resistance overloads.
The most affordable type of solar power inverter is the string inverter. In most cases, these systems are suitable for residential use if the conditions are right for production. The DC power generated by the panels gets sent to a single device for systems using a string inverter once the DC energy is converted to AC electricity by the inverter.
Look at Warranty Information
The length of time covered by this warranty will vary depending on the brand and model of the panel you choose. Still, you must pay close attention when shopping around to know exactly how long your panels will last if anything goes wrong.
Look at the Performance Guarantee
Solar panels get rated for their capacity or how much power they can produce in full sun. But you also want to know that the panel will perform consistently throughout its life.
A guaranteed output percentage (GPO) is the amount of energy a panel is guaranteed to produce over its lifespan. For example, if a panel has a GPO of 90%, it means that in 10 years, it will still make 80% of its original capacity.
Look at Panel Efficiency
The higher the number, the better. The efficiency of your solar panels determines how much energy they can produce about the amount of sunlight they receive. So if you have a panel that’s only 20% efficient, it can convert 20% of the light from the sun into electricity.
However, not all panels are created equal: some are more efficient than others, and some are less efficient than others. For example, some panels may be made with more efficient materials or may even use different technologies that make them more effective at generating power from sunlight.
When shopping for solar panels, you’ll want to look at the panel’s efficiency. The higher the number, the better. Most panels will fall between 17 and 19 per cent efficiency, but if you can find a panel that’s 23% efficient, it’s worth paying for it.
Look at the Watt Density
Watt density is a term that describes how many watts of electricity is generated by a solar panel for every square foot of space. Solar panels with polycrystalline silicon have a higher watt density than monocrystalline silicon. However, the actual watt density depends on the manufacturer and the type of material used to make the solar panel.
A higher watt density means you get more power out of your solar panels, making them more cost-effective. A lower-density panel might save you money upfront but will cost more because it takes longer to generate enough electricity to pay off its initial price tag.
Look at Durability
Solar panels come from different materials, some of which are more durable than others. For example, 90%-95% of solar panels come from silicon, which lasts 20+ years and is non-toxic. However, other solar panels come from glass or plastic, which are less durable but more affordable.
Also, be sure the panels you put in resist the snow and wind. The IEC 61215 is a dependability standard you should consider when purchasing panels.
Look at Aesthetics
Black panels are popular with homeowners. The typical color of a silicone cell is deep blue or black; the solar panels’ faces are of these cells. The back sheet is visible through the gaps between the cells. Having a dark back sheet completes the all-black aesthetic. Also, think about the color of the frame. Silver and black anodized aluminum are solar panels’ most common frame colors. If you want your system to stand out, consider getting a black frame.
Each year, the world gets a little greener. Going solar is a great way to do your part in this movement. A significant factor in helping you make this decision is a resource that can help you identify quality solar panels and installers.
