Gather necessary data

To collect information on the latitude, longitude, and elevation of the desired area, you can start by using online sources or GPS devices. For online sources, go to websites like Google Maps or GPS coordinates data providers. Enter the location in the search bar and find the latitude and longitude information in the address details. Alternatively, use a GPS device to physically go to the location and record the latitude, longitude, and elevation readings.


Determine solar irradiance

To find the average annual solar irradiance for a specific location, you can refer to meteorological agencies or solar resource databases. These sources typically provide information about solar irradiance levels based on historical data and geographic coordinates. Simply access the relevant website or database, input the location’s coordinates, and retrieve the average annual solar irradiance value for that area.


Calculate solar panel efficiency

To determine the efficiency of the solar panels you plan to use, refer to the information provided by the manufacturer. Look for the efficiency rating, which is usually given as a percentage. This rating represents the percentage of sunlight that the solar panels can convert into usable electricity. By knowing the efficiency of the panels, you can assess their performance and make more informed decisions about your solar energy system.


Estimate available roof area

Measure the available roof area where you intend to install the solar panels. Take into account factors such as shading, obstructions, and orientation that could affect the system’s performance. Use a measuring tape or laser distance measuring device to determine the dimensions of the roof area. If there are any obstacles present, ensure that you measure around or exclude them from the total area.


Calculate daily energy production

To calculate the daily energy production of a solar panel system, multiply the solar irradiance (measured in watts per square meter) by the solar panel efficiency (expressed as a decimal). This will give you an estimate of the electricity generated by the system in one day. Simply multiply the solar irradiance by the solar panel efficiency to obtain the daily energy production. This calculation is useful for determining the potential output of a solar panel system on a typical day.


Determine annual energy production

To determine the annual energy production of a system, multiply the daily energy production by the number of days in a year. To do this, simply multiply the daily energy production value by 365 (or 366 in a leap year). The resulting figure will represent the total electricity generated by the system over the course of one year.


Consider solar panel tilt and orientation

Adjust the solar panel tilt and orientation to maximize energy production. Determine the optimal angles based on the latitude and seasonality of your area. Use a solar angle calculator or consult a professional to find the best tilt angle for your panels. Typically, the tilt angle should be equal to the latitude for maximum efficiency. Additionally, orient the panels towards true south (or true north in the southern hemisphere) to capture the most sunlight throughout the day.


Factor in system losses

To factor in system losses, we need to account for various factors that can affect energy output. These include wiring inefficiencies, shading, dirt accumulation, and temperature variations. Consider the following:

  • Wiring inefficiencies: Ensure that the wiring in your solar system is properly installed and sized to minimize resistive losses. Use appropriate wire gauge and keep cable runs as short as possible.Example: “Use 10-gauge wire for long cable runs over 50 feet to minimize resistive losses.”
  • Shading: Assess the shading on your site and design your solar system accordingly. Avoid placing panels in shaded areas to prevent significant energy losses.Example: “Avoid tree shadows by placing solar panels in open areas with maximum sunlight exposure.”
  • Dirt accumulation: Regularly clean the surface of your solar panels to prevent dirt buildup, which can reduce their efficiency. Remove any leaves, bird droppings, or other debris that might hinder sunlight absorption.Example: “Clean your solar panels with a soft brush or hose them off using distilled water to maintain optimum performance.”
  • Temperature variations: Consider the effect of temperature on solar panel performance. High temperatures can reduce panel efficiency, so account for this when estimating energy output.Example: “In hot climates, design your system to allow for natural ventilation and provide space between panels to dissipate heat.”

By accounting for these system losses, you can obtain a more accurate estimation of the actual energy output of your solar system.


Analyze financial viability

To evaluate the financial viability of a solar energy system, consider the following factors:

  1. Installation costs: Determine the total cost of installing the solar energy system, including equipment, labor, and any additional infrastructure required.
  2. Available incentives: Research and take into account any government subsidies, tax credits, or grants available for installing solar energy systems. These incentives can significantly reduce the upfront costs and improve the financial viability.
  3. Electricity rates: Analyze the current and projected electricity rates to understand the potential savings from generating your own electricity through the solar energy system. Compare these rates with the cost of your current energy source.
  4. Payback period: Calculate the payback period, which is the time it takes for the energy cost savings to equal the initial investment. A shorter payback period typically indicates a more financially viable solar energy system.

By considering these factors, you can thoroughly analyze the financial viability of a solar energy system and make an informed decision.
