Understanding Solar Energy
Solar energy entails capturing the sun’s power and transforming it into usable electricity. The most common method of conversion is via photovoltaic cells commonly found in solar panels. It’s an abundant and renewable energy source that emits zero greenhouse gases and reduces our reliance on fossil fuels.
Basics of solar energy
Solar energy utilises the sun’s power, tapping into its rays via solar technologies to produce electricity. At the heart of these technologies are photovoltaic cells, which absorb sunlight and transform it into electricity. This conversion occurs through the “photon” to “electron” method, where the energy of absorbed sunlight detaches the electrons from atoms, generating a flow of electricity.
Benefits of solar energy
Upon embracing solar energy, you reap numerous benefits, including reduced energy bills and decreased carbon footprint. Additionally, it’s a sustainable solution that reduces reliance on limited fossil fuels. It offers energy independence, reliability and scalability, allowing you to add more panels to your system should your energy needs increase.
How solar panels work
Solar panels comprise numerous photovoltaic cells made from semiconductor materials, usually silicon. These cells convert sunlight into an electric direct current (DC). An inverter then changes the DC into alternating current (AC) used to power electrical appliances in your home. A two-way meter sometimes aids in feeding excess electricity back into the grid, thus earning energy credits.

Evaluating Your Home for Solar
Before initiating the solar transition, evaluate the suitability of your home for solar installations. This evaluation involves several steps, from assessing your energy consumption to determining the amount of sunlight your roof receives.
Assessing your energy consumption
Your current energy consumption informs the size of the solar system your household needs. You can acquire your historical and current energy usage information from your utility bills and power company.
Inspecting the condition of your roof
Roof condition is critical in solar installations. The roof should be in excellent condition and structurally sound to support the solar panels—a lifespan minimum of 20 to 25 years and ideally, no shading from trees and other structures.
Understanding the orientation and angle of your roof
The direction and tilt angle of your roof play a pivotal role in the efficiency of your solar power system. South-facing roofs at a tilt of about 30 degrees often yield the best performance.
Determining the amount of sunlight your roof receives
Using solar irradiance calculators, determine the amount of sunlight your roof receives. High solar irradiance factors result in higher system efficiency and vice versa.
Choosing The Right Solar Panels
Having evaluated your home for solar installations, choose the right solar panels for optimum performance. This decision involves understanding the different types of panels and their efficiency.
Different types of solar panels
The two most common types of solar panels are mono-crystalline and poly-crystalline. Mono-crystalline panels, made from a single crystal structure, offer higher efficiency but at a higher cost. On the other hand, poly-crystalline panels, made from different crystal structures, offer lower efficiency at a lower price point.
Factors affecting the efficiency of solar panels
Environmental conditions such as temperature, shade, and the angle of sunlight affect panel efficiency. So do the quality and technology of the solar cells and the inverter. More efficient solar cells and inverters yield higher panel output.
How to choose the right size of solar panels
The right panel size depends on various factors. Your energy consumption, roof space, and financial capacity all go into determining the best solar panel size for your home.
Getting The required Permits
Before installing, seek the necessary permits, complying with all building codes and standards.
Understanding building codes and standards
Familiarise yourself with local building codes and solar installation standards. Such knowledge aids in proper, safe, and legal installations without repercussions.
How to apply for the necessary permits
Apply for the necessary permits at your local planning department. Your chosen solar panel company can help you handle this process.
Document preparation
During the permit application process, have your system’s design and specifications, signed contracts, and proof of compliance with relevant standards and codes ready for submission.
Solar Panel Financing Options
While the initial investment may seem high, various financing options within reach ease the financial burden of going solar.
Solar panel leasing
Under a solar lease, you rent the solar panel system from a company at a fixed monthly rate, bearing no ownership responsibilities.
Solar loans
Solar loans finance the cost of the system, allowing you to pay it off over a specific period. They may be secured or unsecured, with varying interest rates and terms.
Power purchase agreement (PPA)
A PPA involves a company installing, maintaining, and owning the solar system on your property, and you simply for the power the system generates.
Federal and State solar incentives
Various tax credits, rebates, and incentives from federal and state governments reduce the cost of solar installations.
Purchasing Required Equipment
The next step involves purchasing the necessary equipment for the solar installation.
