Frequently Asked Questions

Start by becoming “energy lean”:
– Switch high-consumption appliances to alternative energy sources (e.g., gas water heaters, solar geysers)
– Install a gas hob in your kitchen
– These changes will reduce your energy storage and solar panel requirements, making your eventual system more cost-effective

At Sunlec, we believe in tailored solutions:
– We conduct a detailed assessment of your energy needs and usage patterns
– We can install an energy monitoring device to accurately record your consumption
– Based on this data, we design a system that matches your specific requirements
– We advise against “off-the-shelf” systems that may not suit your unique situation

Not necessarily:
– Oversized systems can lead to energy waste and inefficiency
– At Sunlec, we design systems with expandability in mind
– We can select components that allow for future expansion as your needs grow
– This approach ensures optimal efficiency now and flexibility for the future

Not always:
– We typically recommend a 48V-5kW inverter as an entry-level unit for households
– Smaller inverters (e.g., 3kW) often use 24V systems, which can be less cost-effective for energy storage
– 48V systems generally offer better value in terms of storage capacity per rand
– We’re happy to discuss inverter efficiencies and help you find the most cost-effective solution

While DIY is possible, we strongly recommend professional installation:
– Solar systems involve high voltage equipment with risks of electrocution
– DC installations require specific expertise to prevent fire hazards
– Improper installation can lead to system damage or safety risks
– At Sunlec, we provide certified, experienced installers to ensure your system is safe and efficient

Switching to solar energy offers numerous benefits:
– Reduced electricity bills
– Energy independence from the grid
– Environmentally friendly and sustainable
– Potential increase in property value
– Low maintenance costs
– Protection against rising electricity prices

A high-quality solar panel system can last for decades:
– Solar panels typically have a lifespan of 25-30 years
– Inverters usually last 10-15 years and may need replacement before the panels
– Batteries, depending on the type, can last anywhere from 5-15 years
– At Sunlec, we use top-quality components to ensure longevity and offer warranties on our systems

Yes, with the right setup:
– A grid-tied system with battery backup will continue to function during outages
– The system automatically switches to battery power when the grid goes down
– You can use your stored solar energy or energy generated during daylight hours
– We design systems to meet your specific needs during load shedding periods

Solar systems are generally low-maintenance:
– Panels may need occasional cleaning, especially in dusty areas
– We recommend an annual inspection to ensure optimal performance
– Inverters and batteries might require checks or replacement after several years
– Sunlec offers maintenance packages to keep your system running smoothly

It depends on your specific situation:
– You’ll need permission from your body corporate or homeowners’ association
– Roof space and orientation are important factors
– We can assess your property and advise on the best solutions
– Even if full solar panel installation isn’t possible, we can suggest alternative energy-saving measures

Weather can impact solar panel efficiency:
– Panels still generate electricity on cloudy days, but at reduced capacity
– Rain can actually help by cleaning the panels
– Extreme heat can slightly reduce efficiency, but panels are designed to withstand high temperatures
– Our team considers local weather patterns when designing your system to ensure optimal performance year-round

We offer several ways to make solar more accessible:
– Outright purchase
– Financing through our partner financial institutions
– Potential tax incentives or rebates (we can advise on current programs)
– Our team can help you understand the return on investment and choose the best option for your situation

Solar panels convert sunlight into electricity:
– Photovoltaic cells in the panels absorb sunlight
– This creates an electric field across layers of silicon
– The resulting electricity is converted from DC to AC by an inverter
– The AC electricity can then be used in your home or business

The main differences are:
– Grid-tied systems remain connected to the municipal power grid
– Off-grid systems operate independently of the grid
– Grid-tied systems can feed excess power back to the grid
– Off-grid systems require more battery storage for energy independence
– We can help you decide which system is best for your needs

The number of panels depends on several factors:
– Your average energy consumption
– Available roof space and orientation
– The efficiency of the panels you choose
– Your energy independence goals
– We conduct a thorough assessment to determine the optimal number for your situation

Yes, with a battery storage system:
– Excess energy generated during the day can be stored in batteries
– This stored energy can be used at night or during grid outages
– We offer various battery options to suit different needs and budgets
– The capacity of your storage system depends on your energy requirements

Not when installed correctly:
– Our professional installers use industry-standard mounting systems
– We assess your roof’s condition before installation
– Proper installation can actually protect the portion of roof under the panels
– We ensure all roof penetrations are properly sealed and waterproofed

Several factors determine suitability:
– Roof orientation (north-facing is ideal in the Southern Hemisphere)
– Roof angle and available space
– Shade from trees or nearby structures
– Structural integrity of your roof
– We conduct a thorough site assessment to determine suitability and optimal panel placement

It depends on your system type:
– Grid-tied systems without batteries will shut down for safety reasons
– Systems with battery backup will continue to provide power
– Off-grid systems are unaffected by grid outages
– We can design a system that meets your power needs during outages

We maintain high standards through:
– Using only high-quality, tier-one solar components
– Employing certified and experienced installers
– Following best practices and industry standards
– Providing warranties on both products and workmanship
– Offering ongoing support and maintenance services
