Basic Components of a Solar Panel Kit

All solar panel kits for homes have a series of kernel components. The latter are responsible for creating an electrical charge and then converting it into usable energy that can either be stored or fed into home appliances. For those that want to connect their solar kits to the traditional electric grid, additional modules will be required.

Solar Panels

These are the life of any solar panel kit, as they are responsible for creating electricity with the help of photovoltaic (PV) cells. Solar panels are also the components that are easiest to spot, since they are usually mounted somewhere outdoors, where light can easily reach them throughout the day. They can even be flexible, as these flexible solar panels demonstrate.

Charge Controller

Sometimes referred to as a charge regulator, this element of DIY solar panel kits is responsible for maintaining the appropriate electricity charge. This process is crucial to avoiding battery overcharge and providing generators with energy only when needed. Systems without batteries typically won’t require this part.


Solar panel kits generally produce direct current (DC) electricity. However, all of your home appliances require electricity in the form of alternate current (AC) in order to function. The solar inverter’s job is to convert the former into the latter with as little loss of overall power as possible.

Other Components

If you want to use your solar panel kits for homes in an optimal manner, battery generators are a good idea for storing additional energy to use on cloudy days or to reduce grid electricity consumption. A power/kilowatt/utility meter becomes useful in these conditions, as it enables users to measure how much excess power is fed into the grid by the solar system.

How Many Solar Panels Should You Buy?

How Many Solar Panels Should You Buy

The best way to determine how many PV panels to buy for your DIY solar panel kits is to first calculate your daily electricity load, which is how much power you’d be using every day, on average. Moreover, batteries are a great addition to any homemade system.

Daily Electricity Requirements

The typical daily electricity requirement that your solar panel kits for home should aim for is around 6kWh for an average household, considering that a refrigerator and two light bulbs require just under 1.4 kWh if they run for 8h straight. While you won’t always use in-door lighting for this amount of time, it’s likely that your fridge will stay plugged 24/7. If you’re just powering a few solar lanterns, you’ll need far less obviously.

You can calculate your own daily electricity load by multiplying the amount of time you’d be running an appliance with its required kW. Afterwards, you add the results from all other appliances. Don’t forget to include everything – from refrigerator to microwave ovens, as well as light bulbs.

Choosing the Right Kit

In order to make sure that your solar panel kit can provide enough power, you need to calculate how much your system can produce given a certain amount of sunlight. For instance, a 100W panel will normally give you 400W of electricity if it gets 4 hours of sunlight. To achieve 6 kWh per day with just 4 hours of sunlight, you’d need 15 100W panels.

One thing to keep in mind is sunlight exposure. Some geographic regions get 5, 6, or even 8 hours of good sunlight every day. Rather than banking on the fact that you’d get more, however, it’s wiser to purchase a good generator to go with your DIY solar panel kit. This will ensure that excess electricity will be stored to be used for cloudy days. And if you need the panels to be portable, make sure to stick to portable solar panels as well.

Depending on your location and surroundings, ground mounted solar panel kits might be better than roof ones, as it easier to ensure that your panels are positioned at an angle that can maximize sun exposure. (For a sure thing, check out these Thunderbolt magnus solar kits!)

Off-Grid vs. Grid-Tied Applications

Off-Grid vs. Grid-Tied Applications

Another major decision for your solar panel kits concerns whether you’ll tie them to the grid or not. The grid-tied system takes the excess electricity you generate and feeds it into the traditional network everyone draws their electricity from. If you happen to live in an area where net metering is possible, then you may be able to receive credit for this energy that you feed into the system.

Battery installations for DIY solar panel kits are also popular. Instead of feeding the excess power into the grid, you’d be charging a set of generators that can power your house during cloudy days or night-time. Off-grid systems traditionally seek to maximize power-efficiency by having appliances and lights that are engineered for energy saving, such as DC LED lighting.

Solar panel kits for homes can also be made to go both ways, but it will be costly. Everything you need is a battery system that is good enough to feed excess electricity into the grid once it is fully charged. This version can be cost-effective, as certain systems are capable of generating a hefty amount of power given the right circumstances and location. The advantage for the latter two options is that the batteries can also work as back-up generators in case there’s an outage.

Given how straightforward and affordable DIY solar panel kits are nowadays, it’s truly a bargain to buy one and start saving on electricity bills. Renewable energy is not only a great way to reduce one’s carbon footprint, but also a gateway to lower household costs and achieve energy independence.
