Solar Advisory Services Power / Electricity reliability, costs and availability

is a challenge -• Many institutions / industry / factories / commercial

complexes pay ever increasing costs of electricity without a visible control on their future energy bills.

• Many factories compulsorily run on diesel generators during peak hours as per local ESCOM rules, example Tamil Nadu – evening 6 pm to 10 pm EB power cannot be used. At present diesel prices, the cost of electricity in such cases is Rs 18/- to Rs 21/- per unit, apart from daily cash outflow basis.

Conti……

Solar Advisory Services• For many homes, farm houses, irrigation pumps

are without power for many hours requiring a Hybrid solution of grid with back up.

• New conventional power sources of electricity not on anvil.

• Hydro power suspect in India, depending on regular monsoons.

• Current coal prices are Rs. 5/Kg on regular e-auctions for industries and sometimes Rs. 8/Kg when supply is tight. Prices will only go up!

Why Advantage Solar?Solar PV offers power at Rs.6-7/KWh during daytime use, as either grid connected exporting to grid or as captive depending on size of plant. In case of use with batteries for critical loads, can be configured separately. Diesel• Diesel power costs Rs. 18-21/KWh, (incl logistics,

maintenance) making solar power much cheaper, and also entails daily cash outflow.

• The price of diesel fuel has increased 300% since 2002 and 46% since 2010 and is going to be market driven increasing un-predicatability of energy costs / basket for future. Return on Investment is under 2 years….

Grid• Solar power may be cheaper than grid power,

depending on the customer category and jurisdiction as HT(1), HT(2) etc. For offices and homes tariff slabs are increasing each year… Return on Investment is under 5 years…

How PV system installed?

• Solar panels can be mounted on unshaded roofs, walls or ground using mounting systems.

• DC cables connect panels in series to form strings.

• These strings then feedback to the inverter usually located inside the building as close to the solar panels as possible.

• Every KW of electricity will be recorded on your generation meter.

• A 4KW domestic PV system will usually take 1 day to install.

How does PV work?• Photovoltaics is the direct conversion of light

into electricity. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module, and multiple modules can be wired together to form an array. Photovoltaic modules and arrays produce direct-current (dc) electricity.

• Solar panels capture sunlight and convert it to DC electricity.

• Your solar system's inverter converts that energy to an AC current that can power your home or business.

• Excess energy or energy that you don’t use goes back to the utility grid and creates an electricity “credit” for you to use at a later date.

Process for Net Metering….• This is coordinated by us. Different rules of states apply with regard to system sizing based on distribution transformers. Only Karnataka allows preferential tariff payment for surplus power exported as of now. Other states allow carry forward for a year.• Process : on line application with all the below mentioned documents – 1. Applicant Type 2. Name Of Applicant with Contact details 3. Existing ESCOM Installation Details 4. System size proposed. 5. Rooftop details 6. Subsidy “no claim” declaration to be eligible for tariff given.

Solar Process

Rooftop Solar Systems - Advantages

• General sizes of under 10 KW, 11-50 KW and above 50 KW as per Government categorisation.

• Low Gestation period enabling quick benefit to clients.• Ease of integration into existing systems of either Grid or DG.• No permissions required if connected on load side with

battery for critical loads with no grid export.• No land acquisition or evacuation problems.• Higher financial reliability with visible and predictable cash

flows for energy either in savings or set offs or revenue income if exported.

• Huge savings option against DG which caters to 20 GW in India. Savings to the Nation and protects environment.

• Indirect cooling of building top floor as heat is taken away to great extent by solar panels.

Benefits of Solar

 • Forget about electricity bill for next 25 years and power tariff increase.• Earn money for every unit of power pumped to grid @Rs.9.56/unit.• As a business owner if you are installing solar PV you can claim 80%

of the depreciation in the first year.• Any income received from solar energy is tax exempt for next 10

years. 

Calculations for Rooftop Solar Plant

• Roof Area required : Approximately 100 square feet per 1 KW, clear shadow free area. If sloped roof, then south facing direction slope required with above requirements.

• Tile / Asbestos / Sheet roofs – Solar panels can be installed on these roofs, south facing slope, with accessories. Roof load bearing truss to be checked along-with ageing.

• Area /Weight of solar panels – Generally 16 kgs per square metre. We can help design ideal roofing structure if roof area is to be used below for other possible useful purposes of client.

• System Sizing : We can provide the ideal system sizing for getting good return on investment after site survey inputs and interaction.

Rooftop Power Incentives

• Fiscal benefits to industries – through accelerated depreciation.

• No separate permissions for LT load side integration if no grid export (as solar UPS). Quick roll out time.

• In case of grid connected system, surplus power can be exported with suitable permissions and government pays Rs 9.56 per unit for such power in Karnataka. In other states, power exported is set off against consumption with carry forward for a period of 1 year.

• Presently no subsidies at central level.• Lower cost of equipment at LT level, bringing down

capital and installation costs.
