Currently, most of Sri Lanka is under a system known as Net Metering, which allows your net electricity costs to be reduced to zero, but no further. From 2016 September in the Sri Lanka., youcan be paid for any excess electricity you create, in what is known as a Feed-ln Tariff system.

Net Accounting
If the generated units of electricity using the solar panels fixed on their houses/ premises are greater than the amount he consumed, the customer will be paid Rs.22.00 per unit duringthe first 07years andfrom the 8th yearhewill be paid Rs. 15.50 per unit. If the consumption is greater than he generated, the consumerhasto pay at the existing electricity tariff for the excesselectricity consumed.(NetAccounting).

Net Plus
Getting paid for the amount of electricity generated using the solar panels fixed on their houses/premises. Unlike net metering method there is no linkage in-between the electricity consumption of the customer and the electricity generation.

The customer has to pay for the electricity consumed accordingto the existing tariff. Electricity Board will pay for the total amount of electricity hegenerates. (Net Plus).

People move more frequently now than ever before, but that shouldn't impact your solar decision.

A solar system can save you money today and even pay for itself in as little as five to sevenyears. Evenif you move before your solar investment is completely paid off, studies show the cost will likely be returned in addedvalue to your home.

Plus, your homewill most likely sell faster. Who doesn't want a home with a guaranteed low electric bill? solar panel warranty is eventransferable to the newowner.

Purchase Option OWN/LOAN: If you can afford to a own a system (either cashor loan) and your simple-payback is shorter than the period of workmanshipwarranty, andyou don't mind concerningyourself with maintenance issues, then ownership might be a good option.

There are few general requirements for a loan program, and there may be some specific requirements from your local utility that you will need to clarify with your local installer. That being said, generally speaking:

- Typically you must have an averageelectricity bill of Rs. XXX or more.

- You must own your home, and plan on living there for at least XX moreyears.

This is a great and relevant question and topic. Solar, like many of industries, has become a truly global industry, and like many other manufacturing industries, China has taken a general'lead' intermsofvolume of products manufactured. Take a look at your phone, your computer, your TV, etc.

So, while I support the growth of the Sri Lanka economy as much as anyone, it's difficult to say that you should purchase Sri Lanka made solar panels. Then there is the complication of how solar panels are made and understanding global corporations. Some companies used to manufacture a small percentage of their product in the Sri Lanka, but were Chinesecorporations. There are "Sri Lankan" companies, with headquarters in the Colombo that manufacture in Asia.There are German companies that manufacture in the German.

Ultimately whether you decide to purchase German Made solar panels or solar panels manufactured elsewhere in Asia,

Solar panels will typically operate at 75-85% of nameplate DC power rating, even in weather conditions that might be considered "ideal". The nameplate rating of a solar panel is a DC rating measured under factory conditions (cell temperature of 77º F and "perfect sun" conditions of 1000W/m2). The power output reading seen on an inverter is anAC rating; factors suchas DC to AC conversion losses,wiring losses, temperature losses, lossesdue to shading and dust buildup, and lossesdue to nonoptimal tilt and orientation of the array will affect the instantaneouspower output and cumulative energy production of the solar array.

TheAC power output of a solar array, measuredin watts (W) or kilowatts (kW),istypically given on inverter output displays or remote monitoring sites. lt is an instantaneousmeasurement, determined by the rated DC power output of the solar array, inverter efficiency and system losses, and is proportional to solar irradiance on the array.

The AC energy production of a solararray,measuredin kilowatt hours (kWh), is measured over periods of months and years to compare with sizing and long-term performance expectations. SolarkWh energy production is also typically given on inverter output displays or remote monitoring sites, and can be compared with a household's total kWh electricity consumption, as seen on a utility bill.

Note that for grid-connected PY systems, power generated by the solar PY systemwill first offset anyelectrical loadsin the house, reducing the number of kWhpurchasedfrom the utility.
