Solar is a powerful energy solution that is transforming the world. It’s reducing our dependence on fossil fuels, mitigating climate change, and empowering families.
Solar panels convert sunlight into electricity through the photovoltaic effect, generating direct current (DC). This DC is then converted into alternating current for your home or business. Visit https://www.ellingsonsolarmt.com to learn more.
The third method of solar installation involves a power purchase agreement (PPA). Similar to a lease, homeowners do not own the system itself; instead, ownership is retained by a third-party company that installs and maintains the system. However, unlike a lease, the PPA allows homeowners to purchase the energy it produces at a lower cost than traditional electricity rates. The per-kilowatt hour price can either be fixed or subject to a predetermined escalator, and at the end of the contract period, homeowners may choose to continue with the PPA, purchase the system, or have the third party remove it from their roof.
PPAs are ideal for homeowners who want the immediate benefits of lower electricity costs and a more environmentally friendly source of energy but cannot afford to pay upfront to install a solar system themselves. PPAs also offer homeowners an alternative to utility bills that are increasing at a rapid rate. They are particularly attractive to consumers in regions where electricity rates are high and expected to rise.
Because the third-party owns the system, they assume all risk, including equipment failures and changes in energy market prices. Additionally, a PPA often includes performance guarantees that ensure the system will provide the level of electricity generation agreed upon. This feature is important for customers seeking stability in their energy costs, especially if they have long-term contracts, such as those spanning 10 to 25 years.
Many PPAs include provisions to transfer environmental attributes, such as Renewable Energy Certificates, to the host customer. These are a way to demonstrate sustainability and carbon reduction goals to stakeholders. This is a unique advantage for businesses and organizations looking to gain a competitive edge with their sustainability program or a desire to show measurable value to their investors.
While the PPA is a great option for many individuals, there are some downsides to consider. Most importantly, it can be a difficult choice for homeowners who are interested in selling their home before the contract term ends. Because a PPA is a legal document, liens are placed on a home for the duration of the agreement, which can make it difficult or impossible to sell before the contract is up.
Solar Panels
Solar panels are the heart of any solar energy system. They consist of silicon cells, a metal frame, wiring elements and glass. They also have an insulative layer and a back sheet to protect the panels from excessive heat and humidity.
When sunlight hits a solar cell, it knocks electrons loose from their atoms. When these electrons flow through conductors attached to the positive and negative sides of a panel, it creates electricity. The more solar cells that make up a panel, the higher its power rating. Typically, solar panels contain 60 or 72 solar cells.
Depending on your needs, you can choose from monocrystalline or polycrystalline solar panels. Monocrystalline solar cells are made from one solid silicon crystal, so they have more space for electrons to flow through. They tend to be more efficient, but they are also more expensive than polycrystalline solar cells.
A third option is thin film solar panels. Thin film solar cells are created by spraying or depositing amorphous silicon or cadmium-telluride materials onto a panel’s surface in layers. While they are less efficient than both mono and polycrystalline solar cells, they are lower-cost alternatives that work well for some specific applications.
Once the electricity is generated, it flows directly off your solar panels as direct current (DC). However, in order to be used on a commercial electrical grid, DC must be converted into alternate current (AC). This conversion is done by an inverter, which ensures that your system produces a consistent flow of energy.
Your solar company will help you select the best inverter for your unique system. It may also be able to recommend additional accessories like a solar charge controller and inverter optimizer.
Once you’ve selected the solar panel options that are right for your home or business, your installer will design a system with your local weather patterns in mind. Solar panels perform best in places with plenty of direct sunlight, but even homes in less-sunny regions can benefit from a renewable energy solution. Using your own energy production reduces your dependence on fossil fuels and contributes to a healthier, more sustainable future for all.
Installation
Solar panels are one of the most cost-effective, environmentally friendly, and sustainable ways to power your home. They harness energy from the sun, which travels less than 10 minutes to reach Earth and then converts to electricity that can be used to run lights, appliances, air conditioners, thermal heating systems, ventilation fans, and more. Solar power also has the potential to generate more electricity than is needed, enabling you to sell it to your electric utility company.
The installation of a solar panel system is a complex project that requires specialized knowledge and training. A skilled solar technician can install a grid-tied or off-grid system that reduces your reliance on the power grid, lowers energy costs, and protects the environment.
A solar energy system can be installed on a rooftop or in an open field, and the type of installation will determine its overall cost. For example, rooftop installations are usually more expensive than ground-mounted systems. Also, the type of panel and inverter you choose will influence your installation costs. Polycrystalline and monocrystalline panels are less expensive than bifacial or thin-film panels.
Solar installers are available to provide professional estimates for your system and to assist you in the planning process. It is important to choose a reputable and experienced PV contractor to ensure that your new solar system is installed correctly and to your satisfaction. In addition, the best installers will be able to show you examples of their work and give you an estimate for your particular situation.
If you decide to go with a PPA, a solar company will install, own, and maintain the solar panels on your property. In return, you will purchase the electricity produced by the panels at a price per kilowatt-hour that is lower than the rate charged by your local power company. PPA contracts generally last from 10 to 25 years.

Maintenance
Like your car, solar panels require regular maintenance to ensure optimal performance and efficiency. In addition to cleaning and inspecting the system for damage, solar maintenance services can also include testing the electrical components and optimizing your system for maximum power production.
If your solar panel output is dropping off, the first thing to do is call a trusted and reliable local installer. They will be able to perform a thorough inspection of the system, identify the issue and resolve it before it escalates. This will save you money in the long run and keep your system working at peak performance.
Solar panel cleaning
Your solar panel system can become coated in dust and debris, obstructing the sun’s rays and decreasing your electricity production. Regular solar cleanings can prevent this from happening and keep your panels running at full capacity.
Solar panel repair
Solar panels can be subject to damage due to various factors, including hail and high winds. In the event of a storm, it’s important to contact a trusted solar company for an emergency inspection and repair. They will be able to clean off any debris from your solar panels, replace damaged parts and ensure that all components are functioning properly.
The solar O&M team can also monitor your energy performance online or via a home monitoring system, identifying any potential issues before they develop. If you sign up for a service package, they will also perform a physical inspection of your solar system once a year.
Solar service packages
Unlike many traditional utilities, a reputable solar company is dedicated to their existing customers and offers comprehensive solar maintenance and support plans. These include a warranty and round-the-clock customer support. They’ll also provide you with valuable information about the latest solar technologies, helping you make an informed decision for the future.
