What you should be aware of before buy solar power

Sep. 13, 2023

The future of residential solar photovoltaic (PV) holds great promise, with the technology witnessing rapid global advancements that are expected to further flourish in the decades ahead. However, before investing in solar photovoltaic systems for your home, it's essential to be acquainted with certain key aspects.

Before delving into solar panel installation, it's crucial to assess your home's compatibility, given that solar photovoltaic systems are commonly mounted on the house's rooftop. Consider the orientation of your home – in the UK, for instance, a north-facing roof may not be optimal due to limited sunlight exposure during the day. Conversely, a south-facing roof captures the maximum sunlight. Utilize tools like Google Maps to evaluate the suitability of your roof for solar panel installation.


While roofs are generally designed to support significant loads, flat roofs may have different considerations. If you're contemplating the installation of solar panels on a flat roof, seeking advice from a structural engineer is essential. Additionally, make sure to communicate this to the installation team. Offering detailed photos showcasing your roof tiles can aid the installer in formulating an accurate cost estimate.

Moreover, evaluate whether your roof necessitates any maintenance. If it's showing signs of aging, with damaged tiles or other issues, the installation of solar panels presents an excellent opportunity for renovations. Integrating the solar energy system into the roof allows for the replacement of most tiles, followed by panel installation and the subsequent placement of tiles along the edges. Opting for this approach during a reroofing project can potentially result in cost savings, eliminating the need to install new tiles before mounting the panels. Beyond its practical benefits, this method also contributes to the overall aesthetic appeal of the system.

Determining the load capacity of our roof is crucial. The installation of solar panels on the roof necessitates thorough structural engineering assessments, mandating the installation team to perform on-site inspections. This includes evaluating roof trusses, truss spacing, roof layout, and measuring all relevant weights. Subsequently, this data is forwarded to a structural engineer for detailed calculations. The engineer will then provide documentation outlining whether the installation of substantial solar panels on the roof is approved.

An often overlooked but vital aspect is determining the size of your main fuse, typically found in a gray or black box labeled with its rated value, such as 100 amps. This rating signifies the maximum electrical capacity your home can manage, both in terms of input and output. While many homes have a 100-amp capacity, some may be limited to 60 or 80 amps. In cases where a ring power supply is employed, the size of the power cord entering your home can impose constraints. For accurate assessments, sharing photos of your meter box, including fuses and meters, with your installation team is recommended. This step will assist them in a thorough evaluation of your electrical system.

Calculating the size of your solar photovoltaic array entails multiple factors. While the quantity of panels is a significant consideration, it's essential to refrain from installing an excess of panels. Determining the right size involves evaluating your specific household energy consumption. Align the solar photovoltaic system's size with your energy needs, considering the possibility of producing surplus energy for added flexibility.

Gathering information from your smart meter is crucial during this phase. Reach out to your energy provider to obtain half-hourly usage data, as it plays a pivotal role in helping installation experts precisely ascertain the ideal system size. Sharing specifics about your daily energy usage patterns and seasonal variations will prove immensely beneficial, enabling the customization of the system to align seamlessly with your unique requirements.

Incorporating battery storage is a vital consideration to maximize the advantages of solar energy. While solar panels generate power throughout the day, our electricity requirements persist into the night for essential activities like bathing, dishwashing, and water heating. Securing excess solar energy in batteries becomes imperative to maintain a continuous power supply, particularly after sunset. This strategy prevents surplus energy from being returned to the grid without storage, enabling its utilization during nighttime hours. Upon receiving your information, we will assess your nighttime energy usage—from dusk to dawn—and establish the suitable size for a battery system. Generally, this system can store 10-20 kWh, addressing the majority of nighttime energy needs for most households. However, since individual consumption patterns differ, acquiring accurate data is essential to customize a system size that precisely aligns with your requirements. This personalized approach ensures that your system is neither too large nor too small, delivering an optimized solution tailored to your specific needs.

Suness Lithium Battery Storage Case

Installing solar inverters and battery storage systems necessitates adequate space, considering the dimensions of these devices. Solar inverters, coupled with larger battery storage units, are substantial components that may not be suitable for placement within living spaces. Opting for an appropriate indoor location, such as a garage, is often favored for organized arrangement, ease of maintenance, and accessibility. Given the constraints of indoor space, you might question the feasibility of outdoor installation. Although these products are generally IP rated for outdoor use, exposure to the elements can still affect their durability. While indoor installation is ideal to shield the equipment from potential damage, if outdoor installation becomes the sole option, it can be contemplated with necessary adjustments to mitigate any adverse effects. Striving for a solution that harmonizes functionality with protection ensures optimal performance.

Investing in a solar system constitutes a substantial decision with prospective advantages like reduced costs, diminished dependence on conventional electricity sources, and favorable environmental impacts. Prior to finalizing a purchase, it is essential to comprehensively grasp all pertinent details. Seeking guidance from experts can offer valuable insights to guarantee a well-informed decision.
