Buying Guide

Solar Panels on House

Being the most accessible, affordable, and abundant energy source on the planet, there is no wonder why solar energy is so important and popular. As solar energy does not use any natural resources needed elsewhere on earth, nor does its use harm the environment, solar energy actually reduces the number of contaminants – like carbon –released into the environment. Leaving us with cleaner water, air, and less pollution.

How Does Solar Energy Work?

There are two different kinds of solar energy technologies that turn the sun’s energy into electrical power; photovoltaic cells and concentrating solar power.

Photovoltaic Technology

The most common way of harnessing and using solar energy for your home is using solar panels. Unlike water heaters and AC units that use gas or electricity to operate, solar panels are made up of PV cells (or photovoltaic cells). When the sun releases photons, and light hits the PV cells on your solar panels, the electrons from the atoms travel through the conductor circuit and generate electricity.

Measured in watts, kilowatts, and kilowatt-hours (kWh), solar panels average between 250 – 400 watts, generating roughly 1kWh/ day.

Concentrated Solar Power

Concentrated Solar Power (or CSP) is less common for residential use and typically used in large power plants. The technology begins CSP uses mirrors and reflectors to concentrate sunlight to collect the solar energy and convert it into thermal energy, which harnesses the sun’s heat and turns it into mechanical energy before turning that into concentrated solar power. Once converted to CSP, this energy makes electricity by powering turbines, and it is also capable of storing its energy, which enables it to manufacture electricity any time of day.

How to Pick the Right Solar Company for Me

Solar Company Team

Making the switch to solar can be intimidating, which is why it will serve you well to do your homework and pick a company that will best suit your needs. Before deciding which company to go with, there are certain things you want to look at: licenses and insurance policies, loans and financing options, warranties, and aftercare, and service.

Your monthly energy consumption will determine how many solar panels you will need. Getting quotes from more than one provider is important to ensure you are getting the best fit for your needs. Making sure you get a quality system and panels will ensure you optimize your clean energy.

Take things a step further by installing a power box that is a generator, battery, and inverter all in one. This will maximize not only your energy efficiency but your dollar as well. When thinking about installation, make sure to consider the durability of your mounting system and its ability to withstand the elements and issues relating to weather and atmosphere in your region.

Some states allow net metering, which means if your solar system is connected to the electrical grid, you would be able to sell surplus electricity to utility companies in your area.

Types of Solar Companies

As there are different facets to solar energy, energy companies do not typically offer every piece of the process. Most alternative energy companies tend to focus on one or two areas. Knowing the different types of solar companies will ensure you have well-rounded knowledge to make an educated decision on your solar energy company.

You won’t typically find any one solar company that does everything, as there are so many different aspects that go into harnessing and utilizing solar energy. Understanding what each company’s function is will help you to a better understanding of the overall process.

Manufacturing Companies

Involved in solar energy development and research, solar panel manufacturers are responsible for creating and assembling the solar cells and panels that will be installed on your home. The highest-rated solar companies offer long-term warranties for their products, and they can guarantee quality as they will own their supply chain and assemble their own panels.

Retail Companies

These are the companies you will buy your solar panels from. Working with a network of manufacturers and suppliers, solar panel retailers can provide you with a variety to choose from. They also work with contractors and installers to help you get your solar panel system set up.

Installation Companies

Purchasing your solar panels from an installation company is similar to purchasing your car from a dealership. Solar installation companies directly access the manufacturers and source their solar panels using either a retailer or wholesaler. Solar installation companies primarily focus on getting your panels installed and working on your roof, having obtained the proper knowledge regarding other installation pieces such as inverters or wiring.

Financing Companies

With a large undertaking such as switching to solar energy for your home or business, the cost can be overwhelming. Solar financing companies aid in helping as many people gain access to solar energy as possible. Offering options such as purchase agreements, solar loans, and leases, solar financing companies believe in bridging the gap to cleaner energy. Not sure how to pick the right financing company? Dive a little deeper here.

Installation

Typically for the installation of a solar panel system, customers are looking at a range anywhere from $10,000 – $25,000 (this is before taking into account any incentives or tax credits that could possibly be applied.) Several factors come into play when looking at solar panel installation cost, including the area you live in, eligibility for incentives, type, and number of solar panels you are having installed.

There are federal solar taxes available, which can reduce the cost of your solar panel installation by 30% if you qualify and are eligible. Other state and local government programs also offer incentives that you might be eligible for as well, which could aid in affording the initial costs involved when getting yourself set up with solar power. Homeowners will usually recuperate the installation cost when selling their home

How to Choose the Right Installation Company

Having your solar panel system installed by a professional is crucial in ensuring you get the proper installation of your system. Even though there are Do it Yourself systems, having a professional on hand will ensure your system is securely installed, especially since there are wiring specifics to be aware of.

Reviewing an installation company’s license and certifications, as well as reputation and track-record for their installations, will give you a good feel if the company is a good fit for you. It has been reported that larger solar companies servicing nationwide actually charge more than smaller solar companies for the same – if not lesser quality solar equipment, so getting multiple quotes from installers will help get the best price.

A tip to picking a good installation company is that they do most of the work themselves, using very few subcontractors.

Is Solar Energy Right for Me?

Deciding whether or not to make the switch to solar energy will depend on a few things: how much sunlight your lot receives, how much your monthly energy bill is, and the type of roof your home has.

To optimize and receive enough light to power your solar panels, your home must be in an area with a clear path to receive the sun’s photons for the panels to create the energy to power your home.

To see monthly savings switching to solar, your monthly utility bill needs to be a minimum of $75. If your energy consumption is less than $75 per month, you would see savings in going solar as your electricity usage would not be high enough to balance out.

How to Tell if Your House is Right for Solar

You want to review several things about your house to make sure you can take your house off the grid and use solar panels to power your home.

Roof Size, Structure, Position, and Condition

Making sure your roof is solar panel friendly means looking at several aspects of your roof. To obtain maximum efficiency of your solar panels, you will want to install them facing south (in the northern hemisphere) to face the sun’s rotation. As many quality solar panels last for at least 40 years, they need to be installed on a roof with the same life expectancy.

The mounting hardware that comes with the solar panel is most compatible with shingles (asphalt or composite), standing seam metal, concrete tiles, and other durable materials. If your roof needs repair, consider doing that before having your solar panels installed

The size of your roof also needs to be considered when determining if solar energy is right for your home. Solar panels are 5 ½ ft by 3 ½ ft, so depending on how many panels will fit on your roof, you can calculate how much energy you will be able to produce, ultimately determining if your roof size can accommodate enough panels to make a savings in switching to solar energy.

Amount of Sun Your Roof Gets

The more direct sunlight solar panels get, the more power they produce. By calculating peak sun hours in your area, solar companies can see how much electricity your home can produce. To calculate your own peak sun hours yourself, take an insolation meter, and place it in direct sunlight. This will measure light intensity and the potential supply of solar power in your area. Typical sun peak hours in the United States average from three to five hours, with hours decreasing in the winter and increasing in the summer.

Location

Solar energy is more easily accessible in some states than others. With the solar industry exploding in California as the state invested $46 billion into renewable energy, some states support the energy source a lot more. Climate is another factor that impacts the amount of energy you require; cooling or heating units need to be run constantly, for example.

Large buildings, trees, or other obstructions that will interfere with how much sunlight will reach your panels will make them less effective, possibly rendering the savings not worth making the switch.

Add Value to Your Home

Not only does investing in solar energy benefit the environment and your monthly electricity bills, having a solar panel system on your roof will add value to your home when going to sell it. Being environmentally conscious and responsible is more popular than ever. Having a home set to run off clean energy is an added bonus that will give you more back on your investment when selling your home.

What Happens to Your Solar Panel System if you Move?

Even though it is technically possible to bring your solar panel system to your new house, the amount of money involved in the process, from removal costs to transport and re-installation, the cost is incredibly significant, so it may not be financially feasible to take them with you.

Despite the enormous undertaking your wallet would take, there is potential for the solar panels to become damaged during their transport. If you did not buy your solar panel system outright and are leasing them, these leases can typically be transferred over to the new buyers; however, if you did purchase the system outright, it is something you should speak to your real estate agent about to add it into the price of your home when selling.
