Installing a domestic solar power system can be intimidating for many people, in part because of the technical lingo that can be overwhelming. What’s the difference between “photovoltaic cells” and “solar cells?” And, of course, there’s the matter of batteries.

Residential solar power setup isn’t as complicated as you would imagine – and you may not even require battery storage!

Compare solar cells with those that use photovoltaic technology.

Here are some definitions for you. Is there a difference between a photovoltaic and a solar cell? No, they’re all referring to the exact same thing!

Simply put, “photovoltaic” refers to the process of transforming light into energy. A PV cell, short for photovoltaic, is another name for a solar cell.

Silicon wafers are sandwiched between a special form of glass that is resistant to temperature changes and some degree of flexing in order to create a solar cell.

electron activity increases when solar cells are exposed to sunshine. A solar panel generates direct current (DC) electricity by connecting an array of photovoltaic cells (also known as an array) via cables that trap electrons.

solar regulator (charge controller) or power inverter, which converts the DC to AC – ready for use in the home, via wire from the solar panel of solar cells, respectively.

Solar power systems for residential use are quite basic and do not have moving components, so they are extremely long-lasting and require no upkeep! A lot of solar power systems that were installed in the 1970s are still going strong.

You may now nod sagely when someone talks about photovoltaic cells at a party and know exactly what they’re talking about.

Is it necessary to use rechargeable batteries?

When using a “grid-connected” system, you don’t need to worry about bringing in extra batteries. This simply implies that the solar cells’ electricity isn’t kept in your house and that you’re still hooked up to the grid.

Solar/photovoltaic cells generate electricity that is sent back into the grid if it is not immediately needed by your appliances or if surplus electricity is produced. It’s a seamless procedure that doesn’t require your involvement if you’re not creating enough to meet your needs. “Net metering” is the term for the practice of metering and crediting excess electricity generated by solar panels, wind turbines, and other renewable energy sources.

As a result of the excess electricity generated by a grid-connected household solar power system, some people are actually paid by their utility! Feed-in tariffs are the term for this type of arrangement.

As one of the few negatives of grid-connecting your home’s solar electricity, you’ll be in the same situation as your neighbors in the event of a blackout. In the event of a power outage, your inverter will shut down to protect your electronics from damage and to keep electricity from reentering the grid.

Battery backup systems are an option if you need constant, uninterrupted power. People who live in isolated places where it is difficult to gain a connection to the mains supply can save money by using batteries. Many governments are now offering discounts on stand-alone household solar power equipment, making this type of system, also known as a SAPS (Stand Alone Power System) or off-grid system, a significantly more cost-effective option than a grid-connected system.

What kind of batteries do I need to purchase?

The use of automobile batteries for solar power storage has been attempted by some, however this is only a temporary fix. Constant draw and deep discharge over lengthy periods of time is simply not what car batteries are built for. It’s recommended to go with deep cycle batteries because they’ve been designed for continuous charging and recharging over a long length of time.

Floating, gel, and AGM batteries are all forms of deep cycle batteries. Because these batteries have an immobilized electrolyte (acid), the later two are a better option. Silica is added to gel batteries and glass mats are put between lead plates in AGM batteries in order to achieve this.

Immobilized acid makes the batteries safer to use because there are no spills or off-gassing (the gases from batteries are highly explosive), and it extends their service life..

Ask a pro and you’ll save a lot of money.

Before you start shelling out cash on solar cell panels, deep cycle batteries, and other parts, it pays to speak with an expert in the industry about your specific needs if you’re intending to invest in a domestic solar power setup for your home. They have the expertise to make recommendations on the best equipment for your needs and will be aware of any available rebates for domestic renewable energy. The time and money you save by consulting a household solar power professional might be enormous!
