Solar Rooftops
A rooftop solar power system, often known as a rooftop PV system, is a photovoltaic (PV) system with electricity-generating solar panels installed on the roof of a home or business. Technology, modernization, and mechanisation have created a never-ending demand for electricity, which is reflected in our sky-rocketing electricity bills. In our efforts to meet the ever-increasing demand for electricity, we are contributing to the depletion of natural resources, pollution of the environment, and dangerous climatic change. Alternative and renewable energy sources are the only solutions to this impending problem. And solar energy will be a driving force in making the earth a greener, cleaner planet.
A solar PV rooftop system is essentially a small power plant that is installed on your roof. Three essential components make up the Grid Interactive Roof Top Solar Photo Voltaic (PV) system. Solar PV modules, mounting structures for the modules, and inverters, or power conditioning devices. Solar PV modules are arranged in an array, which requires a mounting structure to keep the modules at the proper angle for maximum generation. Solar panels convert solar energy in the form of light into direct current (DC) power (Direct Current). The inverter/power conditioning equipment converts DC electrical energy to AC (Alternate Current) electricity, which is then connected to the power grid via an AC distribution board. A metering panel linked to it can be used to measure the AC power output. Depending on solar power generation and local demand, the system’s output can be synchronised with the grid, and electricity can be supplied to the grid.
How does a solar rooftop work?
Rooftop solar panels rely on the solar cells’ capacity to capture the sun’s energy and convert it to power. It is made of a tiny, square-shaped semiconductor that is produced from conductive materials such as silicon. When sunlight reaches the solar cells, chemical processes occur, releasing electrons and resulting in the generation of electric current.
Types of solar photovoltaic solutions
Residential
Solar rooftop for home installation is a cost-effective option for practically anyone to get started on a greener, cleaner, and less expensive path ahead. Installing a solar power system will immediately increase the value of your home.
Commercial & Industrial
Solar rooftop systems for commercial and industrial buildings will provide a strong return on investment by utilising unused roof space. Nuetech Solar, with its first calss prodicts and efficient engineers, can tailor solar solutions to meet your needs.
Institutional
Solar rooftop systems help meet the energy needs of institutions such as schools, colleges, universities, research organisations, and non-profit organizations.
Solar PV systems that operate on the grid do not require batteries for storage. Different types of inverter technology can be used to suit your needs and convenience.
A hybrid solar PV system is a perfect integration of batteries and the grid. Existing loads are handled first, followed by charging batteries, and finally connecting to the grid.
An off-grid system is a solar PV system that is completely off the grid. Solar energy feeds the batteries in this system, and energy is delivered to loads from the batteries.
A solar water pump is a complete water pumping system that runs on solar energy via photovoltaic panels. The employment of a solar water pump for irrigation is extremely beneficial. Solar street lights use solar energy to brighten streets or other open areas. Solar street lights are an excellent, cost-effective solution not just for city dwellers, but also for those who live in rural areas without access to energy.
When to select the hybrid solar system?
It makes sense to install a hybrid solar energy system if you have situations like –
- Low feed-in tariff: Hybrid power systems are worth installing in areas where feed-in tariffs are low. Solar panels operate at their peak throughout the day, especially around noon, but because household use of electricity is often lower during this time, the majority of the surplus energy is exported to the grid at a cheap cost per unit of electricity. However, if the solar panels do not create enough electricity in the evening, we must import it from the grid, which is more expensive than the cost gained when exported.
- Frequent power blackouts: Installing a solar hybrid system in a location with frequent blackouts and a low feed-in-tariff rate is a reasonable option, but one must ensure that a suitable backup system is in place to run crucial loads.
Pros
- Reduced reliance on the grid
- Hybrid inverters include backup power capacity, ensuring that electricity is available at all times. It allows customers to use power from the grid, batteries, or solar panels, ensuring the power is uninterrupted.
- In the event of a power cut, a hybrid solar energy system can be used as an off-grid solar energy system.
- During days when the sun fails to come out or during peak evening hours (when tariff rates are high), stored energy can be retrieved, resulting in lower electricity bills.
Cons
- Installation is not simple and costs are higher.
- Maintenance costs are also higher owing to the need for battery replacements on a regular basis.
- Backup power is only provided for important loads, and not all appliances are supported.
FAQs
This, of course, is dependent on the user’s location and requirements. If you want to be fully independent of the grid, an off-grid system is a feasible choice. It is also an excellent option for rural places where grid access is difficult or areas with frequent power failures. However, it is necessary to ensure that the battery has sufficient storage capacity to accommodate all of the demands.
When the solar panel is unable to generate enough electricity for days and the battery is depleted due to overcast weather, a hybrid energy system is a better option. The hybrid system can switch to the grid system in this situation. A hybrid solar power system is also a more reliable solution to assure a consistent power supply by combining grid, battery, and solar if you live in an area with adequate utility grid connection (few power outages).
To answer this question, you’ll need to know the location of the installation, the power requirements, and the user’s budget. However, if you live in an area where power outages are common, hybrid solar energy systems are an important alternative to ensure constant power.
In a grid-connected or hybrid solar system, net metering is a type of solar incentive for minimising the electricity cost. The local utility provider will compensate for the extra energy exported to the local grid link, based on the state and distribution company’s policies.
Yes, a battery backup can be added to an existing system along with a compatible inverter; the quantity of batteries to be added depends on the individual requirements.
A hybrid system is an excellent way to keep your power supply under control. With solar panels and a backup battery, you could be your own energy supplier with the added security of being linked to the power grid.
Hybrid systems save money by lowering your electricity bills, making the higher initial system costs worthwhile. Instead of selling it back to your utility, your solar battery will store the majority, if not all, of the excess electricity your system produces. While net metering credits will not appear on your utility account, you will still receive the same value for your electricity.
The fact that you will be covered during adverse weather and evening use is what sets a hybrid system apart. You have a fully charged backup battery and access to grid power if you require more energy than your battery can offer, and vice versa. With a hybrid solar system, you can always stay powerful.
