Solar Panel Installation: Photovoltaic Vs Thermal (Unpacked)
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Determine energy needs | Before deciding on which type of solar panel to install, it is important to determine the energy needs of the household or business. This will help in choosing the appropriate size and number of panels. | Failure to accurately determine energy needs may result in under or overestimating the required number of panels. |
| 2 | Choose between photovoltaic and thermal collectors | Photovoltaic panels convert sunlight directly into electricity while thermal collectors use the sun’s energy to heat water or air. Photovoltaic panels are more efficient in converting sunlight into electricity, but thermal collectors are more efficient in converting sunlight into heat. | Choosing the wrong type of panel may result in lower efficiency rates and higher costs. |
| 3 | Assess climate impact | The climate of the installation site should be assessed to determine the amount of sunlight available throughout the year. This will help in determining the efficiency rates of the chosen panel type. | Failure to assess the climate impact may result in lower efficiency rates and higher costs. |
| 4 | Analyze installation requirements | The installation requirements for each type of panel should be analyzed to determine the feasibility of installation. Photovoltaic panels require a large surface area and should be installed on a roof or open ground while thermal collectors require a smaller surface area and can be installed on a roof or wall. | Failure to analyze installation requirements may result in improper installation and lower efficiency rates. |
| 5 | Consider maintenance requirements | Both types of panels require regular maintenance to ensure optimal performance. Photovoltaic panels require cleaning to remove dirt and debris while thermal collectors require flushing to remove mineral buildup. | Failure to properly maintain the panels may result in lower efficiency rates and higher costs. |
| 6 | Evaluate cost analysis breakdown | The cost analysis breakdown should be evaluated to determine the total cost of installation, including incentives and rebates. Photovoltaic panels are more expensive to install but have a higher return on investment while thermal collectors have a lower upfront cost but a lower return on investment. | Failure to evaluate the cost analysis breakdown may result in higher costs and lower returns on investment. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Photovoltaic and Thermal solar panels are the same thing. | Photovoltaic (PV) and Thermal solar panels are two different types of solar panel technologies with distinct functions. PV panels convert sunlight into electricity, while thermal panels use sunlight to heat water or air for space heating or hot water supply. |
| Solar panel installation is expensive and not worth it. | While the initial cost of installing a solar panel system can be high, it pays off in the long run by reducing energy bills and increasing property value. Additionally, there are various incentives available that can help offset the upfront costs of installation. |
| Solar panels only work in sunny climates. | While solar panels do perform better in areas with more sun exposure, they still generate power even on cloudy days or during winter months when there is less daylight hours available. In fact, some countries like Germany have successfully implemented widespread use of solar power despite their relatively low levels of sunshine throughout the year. |
| Installing a home battery storage system is necessary for using solar power at night. | It’s not always necessary to install a home battery storage system if you’re connected to the grid as excess energy generated during daytime hours can be fed back into the grid for credit towards your utility bill through net metering programs offered by many utilities companies across North America. |
| Solar panel maintenance requires frequent cleaning. | While keeping your PV modules clean from dirt and debris will improve their efficiency over time, most modern systems require little maintenance beyond occasional visual inspections to ensure everything looks normal. |
