What Will a Solar Roof Cost You in 2022: Is a PV System a Good Investment

by Kremy

With electricity prices constantly rising, many homeowners are wondering what an investment in a solar roof would cost them in the current situation. Those who install a photovoltaic system (PV system) have numerous benefits, such as lower utility bills, reduced carbon footprint and potentially higher property values. However, these benefits usually come with significant installation and maintenance costs. The extent of winnings can vary greatly from house to house. Now, this article aims to help homeowners make the financial calculations needed to determine the viability of solar energy in their homes.

How Much a Solar Roof Can Cost and Which Factors Have To Be Considered with Photovoltaic Systems

Those looking to live greener in 2022 might consider solar panels for their home. While costs have come down in recent years, solar panels can be quite expensive to install and maintain. In addition, solar panels are particularly suitable for houses that receive ample solar radiation throughout the year and can provide pool heating as well. Before you decide to invest in solar energy, you should understand both the social and economic factors.

Photovoltaic systems have been developed as solar technology since the 1950s. Thanks to falling prices for solar collectors, however, this renewable energy has only been considered economically viable and widely used since the 2000s. The size of the solar modules is an indication of the theoretical electrical output potential in watts. However, the typical realized power of installed photovoltaic systems, known as the “capacity factor”, is between 15% and 30% of the theoretical power. A 3 kilowatt-hour (kWh) home system working at a 15% capacity would produce 3 kWh x 15% x 24 hrs/day x 365 days/year = 3,942 kWh/year, or about a third of the typical household electricity consumption.

How to Calculate the Solar Roof Cost As a Homeowner

However, the calculation described above can be misleading as there is little reason to speak of “typical” energy consumption. In fact, solar energy can make sense for a household, but not every house. This discrepancy may be due to the financial and practical considerations that must be taken into account when determining profitability. Having in mind the primary cost for purchasing the equipment, solar power requires a large initial investment. Thus, a solar module almost certainly represents the largest single item of the total costs.

Other equipment required for installation includes an inverter, which converts the DC power generated by the panel to the AC power used by household appliances, and meters to monitor power production. This also includes various components such as cables and switching devices. Some homeowners are also considering a photovoltaic system with storage. Additionally, as a single or duplex homeowner, you should also consider the labor cost of installation. Before you buy solar panels, it’s best to get quotes from several reputable installers to calculate value for money.

When You Could Decide to Go for a Solar System?

Using solar panels and solar attic fans saves money on your electricity bills, and the panels can still generate some electricity on gloomy days, which is vital when the weather is often so gloomy. In the beginning it is helpful to know how much a solar roof would cost. However, the primary factor that determines the value of solar systems is your location. Additionally, location assessment goes into how much sunlight your area receives and takes into account your electricity bills, solar power costs by location, local solar power, etc.

Solar panels are a good (or better) investment for homeowners who meet a few specific criteria. It is important to understand that when you buy a solar system, you are paying for electricity for 25 years in advance. So think about what you would spend on future utility bills. This will give you a better idea whether it is worth installing solar panels in your home.

So if you want to buy solar modules, you have to calculate differently than before. This is because the price of electricity rather than remuneration plays the most important role. In addition, electricity is currently being stored for personal use rather than for sale. Some homeowners are also considering battery storage. In the past, batteries were too expensive and unnecessary when the utility pays for excess electricity fed into the grid. You also have to factor in the labor costs for installation. In addition to the installation costs, there are a few other costs associated with the operation and maintenance of a solar photovoltaic system.

Factors That Will Help You Save Money on a Solar Roof

Factors to Save Money on a Solar Roof

Your house receives a lot of sunlight. If your place of residence gets a lot of sunlight all year round, you are probably getting more from your solar panels. However, if your house is shaded by trees or other houses, the solar panels may not be worth the investment.

You have enough space on your roof. Installing a solar system means that you need a lot of surface area on your roof. This area should not be obstructed by skylights, chimneys, etc. This does not mean that if you have small roof surface you cannot install a PV system. However, in this case you need to find the most efficient solar panels, which are correspondingly more expensive. Also, on roofs with steeper pitches, it is even more difficult to install the panels, which could also result in higher labor costs.

Your roof faces south or west. Homes with south, southwest, or west-facing roofs receive more direct sunlight, which means more energy production.

You have high utility bills. The amount of money you save when you switch to solar energy is directly proportional to the amount you spend on electricity bills each month. So if your electricity price is pretty high, you can make bigger savings by switching to solar.

The city encourages solar energy and offers rebates or tax exemptions. If your utility offers high tariffs or a low buyback rate for solar power, it may be best if you wait.

What the Current Prices Look Like and What a Solar Roof Would Cost

Even though the price of solar panels has fallen much faster than expected, such a home energy system is still a significant investment. Like any other investment, you can expect a positive return on solar panels in the future. If you choose a photovoltaic system, however, the prices can vary greatly. Depending on the size, the costs for a solar roof have to be calculated differently. Your location can determine whether the system will pay itself back over time. This is because you don’t spend as much money to buy electricity from your utility. Depending on where you live and the size of your system, it can take an average of 10 to 20 years before it is profitable.

cost calculations for installing a photovoltaic system

The average gross price is between EUR 9,500/USD10,500 for small roofs and around EUR 19,000/USD 21000 for large roof areas. However, this also includes all additional costs including commissioning. For example, 6 square meters/ 64 feet of solar panels on your roof can generate approximately 1 kilowatt hour. In this way, between 950 and 1,200 kilowatt hours of electricity can be generated. A normal photovoltaic system generates between 4 and 10 kilowatt hours in private homes. So if you have properly assessed, planned and executed the installation, solar energy is a wise investment to make. Solar panels are worthwhile for the majority of customers, but there are certainly some exceptions.

Pros and Cons of Solar Panels for Your Home

Like most investments, solar energy has its pros and cons. At the same time, some economic costs can be covered through the social environmental benefits and reduction of your carbon footprint, which goes beyond a purely monetary assessment. In practice, for example, it is often not possible to supply a house with solar energy alone, because solar only works when the sun is shining.

This means that you cannot generate optimal electricity at night or when the sky is cloudy. There are some battery solutions to provide power during such times, but they tend to still be quite expensive. Most homes with solar panels therefore still rely on the grid from time to time. Despite supply chain problems, the cost of solar energy is close to an all-time low, which could last until the end of 2022 due to the events in Ukraine.

However, there are some exceptions, such as too much shade on the roof, not enough roof space, or already too low electricity bills to justify the purchase. Solar panels are not a perfect source of energy for everyone. Disadvantages include lower efficiency when facing in any direction other than south or west. Additionally, there are potential complications with a solar lease or loan when selling a home.

economical strategy for renewable energy sources

In order to find out if solar panels are beneficial for you, it is recommended to contact a supplier. Even if the cost of solar power turns out to be higher than electricity purchased from a utility, homeowners could potentially install solar power to avoid future potential swings in energy costs. Otherwise you only look beyond your personal financial motives and use of solar energy for the purpose of “green living”.
