In a solar rooftop system, the solar panels are installed in the roof of any residential, institutional, social, Government, commercial, industrial buildings etc.. This can be of two types:
- Solar Rooftop System with storage facility using battery
- Grid Connected Solar Rooftop System
In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit/Inverter and is fed to the grid either of 440/220 Volt three/single phase line or of 33 kV/11 kV three phase lines depending on the capacity of the system installed at residential, institution/commercial establishment and the regulatory framework specified for respective States. These systems generate power during the day time which is utilized by powering captive loads and feed excess power to the grid as long as grid is available. In case, where solar power is not sufficient due to cloud cover etc., the captive loads are served by drawing balance power from the grid.
- Solar PV Modules/Solar Panels
The Solar PV modules/Solar Panels convert solar energy to electrical energy. They are available in different technologies such as crystalline, thin film, CIGS, CdTe, HIT, etc. Crystalline Solar PV panels are most common in use on roof tops.
Inverter converts DC output of Solar PV panels into AC power.
- Mounting structure
The mounting structure, is the support structure that holds the Solar PV panels.
- Balance of System
These consist of cables, switchboards, junction boxes, meters, structures, tracking system (if required), earthing system ,circuit breaker,fuses etc.
- CAPEX Model
Here, the entire system is owned by the rooftop owners and he bears the cost of the Soalr system. Responsibility of O&M for the system lifetime (25 years) is also with the rooftop owner. Developer is responsible for installing the system and initial 2 years O&M and five years warranty.
- RESCO Model
Here, the entire system is owned by the developer. Responsibility of O&M for the system lifetime (say about 25 years) is also with the developer. Rooftop owners may consume the electricity generated, for which they have to pay a pre-decided tariff on a monthly basis. Excess generation may be exported to the grid, subject to availability of requisite state regulations
For consumers that have adequate manpower/expertise for O&M, rooftop access concerns, availability of funds upfront, CAPEX model is better. Consumers in states that have net- metering regulations can take benefit of the same in case they have substantial excess generation.
On the other hand, consumers who prefer not to take responsibility for the system O&M, do not have rooftop security concerns and prefer to pay on a monthly basis rather than bulk upfront payment may choose to go for RESCO model.
The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when it is raining, and no energy at night.
All of you install an on-grid solar system which meets your requirement, then you can reduce your electricity bill by 90%, the only charges you have to pay is fixed charges set by the kseb.
If your solar panel system is connected to the grid, it will turn off in the event of a power cut. This is to prevent emergency responders and electricity utility repair-people from being injured by your panels sending power back to the grid. However, there are certain inverters you can buy that provide backup power in a blackout when paired with a battery.
Solar energy systems can last for 25 to 35 years, and it can be costly to remove and reinstall them if you need to replace your roof. If your roof needs maintenance in the near term, you should complete it before you finish your solar installation. One of Golden ray pre-screened solar installers will be able to tell you whether to replace your roof before going solar.
Simply put – the sooner you get solar, the sooner you will enjoy its benefits! If you wait for some unproven technology down the road, you will have missed the opportunity to generate your own power now. Solar is like saving for retirement – the sooner you start doing it, the better.
Our typical residential solar power job takes 1 week depend on the roof type and kw of the system need to install ,if 3 kw solar system on flat roof will take 2-3 days of installation.
Our team also delivers the general informations that people always wanted to know. This will make more familiar to our services and projects in most efficient and transparent manner
The grid connected rooftop system can work on net metering basis wherein the beneficiary pays to the utility on net meter reading basis only. Alternatively two meters can also be installed to measure the export and import of power separately. The mechanism based on gross metering at mutually agreed tariff can also be adopted.
Solar panels absorb the sun’s energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid
Grid-tied solar electricity offers a way to fix your electricity rate for more than 25 years. The maintenance-free panels come with a 25-year production warranty and the expected useful lifespan is up to 40 years (output starts to slow down over time but is still significant). A grid-tied PV system can protect you from electricity price increases for decades. That’s a feeling of energy security that is hard to duplicate.
Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.
Think of your solar Panels has a 25-year investment. Solar panels will produce electricity for at least 25 years. Panels will continue to generate electricity after 25 years but at a decreasing rate.
When you install a solar energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. How much you can save depends on the electricity rates but going solar is a smart investment regardless of where you live.
1 kilowatt (KW)of the solar panel takes about 100 square feet. Nowadays panels technology is improving and much efficient panels can reduce the space required.
The size of your solar energy system will depend on how much electricity you use on a monthly basis, as well as the weather conditions where you live. Make an appointment with Golden ray expert to learn more about your system size .
Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you need to clean your solar panels regularly(6 months). If something does happen, most equipment manufacturers include warranties, although warranty terms depend on the company.
Southerly-facing roofs with little to no shade and enough space to fit a solar panel system are ideal for installing solar. However, in many cases, there are workarounds if your home doesn’t have the ideal solar roof. If the roof is not south facing or have done truss work it is ok we can do it with some extra structure work to make it suitable for going solar.
Though the capital cost of a Solar Power plant System is higher than a DG System, a DG System accounts for a high fuel cost and maintenance cost. While a Solar Power plant System doesn’t require any fuel and its maintenance is very minimal and easy. Apart from this, a Solar Solar Power plant System is a clean and environmentally friendly option for a backup system.
