4. Solar power will not be the only source of electricity

If you choose an on-grid solar system, your home will be connected to your city’s electricity grid to make sure a continuous source of power when required. This is especially helpful if you live in a place that doesn’t have rational sunlight or where sunlight is not ample many months out of the year. Some property owners choose to live off the grid, depending on battery storage and generators. This type of installation will require a professional and experienced solar panel installer who knows how to do this.

5. Which type of installation is best for you: Rooftop solar system, or ground-mount?

The choice between a rooftop solar system and a ground-mounted system depends on various factors, including your specific needs, available space, and preferences. Here are some considerations to help you decide which type of installation is best for you:

Rooftop Solar System:

Space Constraints: Advantage: Rooftop systems are ideal if you have limited land space. They make efficient use of available roof area, especially in urban or densely populated areas. Aesthetic Considerations: Advantage: Rooftop installations are often less obtrusive and may be more visually appealing, especially if you are concerned about the aesthetics of your property. Energy Efficiency: Advantage: Rooftop systems can be more energy-efficient due to their proximity to the point of use. There are fewer transmission losses compared to ground-mounted systems. Permitting and Zoning: Consideration: Check local permitting and zoning regulations. Rooftop installations may have fewer regulatory hurdles compared to ground-mounted systems. Shade and Obstructions: Consideration: Ensure that your rooftop receives adequate sunlight throughout the day. Shade from nearby buildings or trees can significantly impact the performance of rooftop solar panels. Structural Integrity: Consideration: Assess the structural integrity of your roof. Ensure that it can support the weight of solar panels and withstand the additional load, especially in areas prone to heavy snow or strong winds. Installation Costs: Consideration: Installation costs for rooftop systems are generally lower because they utilize existing structures. However, factors like roof condition and orientation can affect costs.

Ground-Mounted Solar System:

a. Available Land: Advantage: Ground-mounted systems are suitable for properties with ample available land. This option is more feasible for larger-scale installations.

b. Optimal Sun Exposure: Advantage: Ground-mounted systems can be positioned to optimize sun exposure, especially if the orientation and tilt of your roof are not ideal for solar panels.

c. Maintenance Accessibility: Advantage: Ground-mounted systems are often easier to access for maintenance and cleaning, as they are at ground level.

d. Potential for Tracking Systems: Advantage: Ground-mounted systems may allow for the use of tracking systems that follow the sun's path, optimizing energy production throughout the day.

e. Roof Integrity: Consideration: If your roof is not suitable for solar panels or requires extensive modifications, a ground-mounted system may be a more practical option.

f. Potential for Expansion: Consideration: Ground-mounted systems offer more flexibility for expansion if you plan to increase your solar capacity in the future.

g. Installation Costs: Consideration: Ground-mounted systems can have higher installation costs due to the need for additional infrastructure, such as support structures and foundations.

Hybrid or Dual Systems:

a. Combining Rooftop and Ground-Mounted: Advantage: In some cases, a combination of rooftop and ground-mounted systems might be the optimal solution. This approach allows for maximizing energy production by using available roof space and utilizing additional land.

b. Energy Storage Integration: Consideration: If you are considering energy storage solutions (such as batteries), evaluate whether rooftop or ground-mounted systems are more conducive to integrating storage technology based on available space and access. Ultimately, the best choice depends on your specific circumstances, goals, and constraints. Consulting with a reputable solar installer and conducting a thorough site assessment can help determine the most suitable installation type for your needs.

6.Excess production of solar energy.

The production of solar energy more than our needs might be one of the problems that everyone would like to face. Solar energy systems normally hit the highest electricity production in the afternoon, when many people aren’t home using electricity.
