Japan is a very specific case due to Fukushima and high tariff support was justified to create business opportunity and also to increase the consumer spending as this country was in long recession of over 20 years and we can't compare with such ideas only on Capacity addition. Now, the tariff is reduced there also... Still the base load is a problem in Japan too and needs to depend on imported raw material be it Coal or Uranium / Gas etc .

Germany after playing election drama or games with roof top solar PV with high tariff support has now reduced the tariff and will also take few more drastic steps too, so, do not copy or APE German system (like Gujarat played in 2009 to 2011 during elections to support with high tariff of rs.15/kwh)...

China: We must congratulate China for its inward thinking. They faced the trade-war on solar components by suitably deviating national outlook by framing the required solar policy to generate internal demand for solar components. They are targeting to add 14 GW solar installed capacity in 2014. Previous record was 7.5 GW by Germany (2011). Establishment of manufacturing centres for solar components is the primary need for India’s solar growth. As BTI has assessed India has a solar potential of 1000 GW (Equivalent to 1000 nuclear plants). India can spend their time and energy to accomplish this target of 1000 GW making India a GREEN NATION.

With many areas providing over 2,000 peak sun hours per year of insolation and plenty of land available, the potential is almost unlimited. Some challenges remain, e.g. sensitivity of solar modules to blowing sand and salt water, as well as long-term performance of all components (modules, inverters and BOS) in extremely hot environments. Thin film might offer solutions due to the temperature coefficient, but not enough data exists yet for very high ambient temperatures. In terms of geography, Saudi Arabia, the Emirates and Oman all have done at least some work on solar and steam seems to be gathering for further initiatives (e.g. rooftop C&I program in Abu Dhabi).

Indeed on top of the number of issues relating to the growth of the solar industry is the credit markets the impact of the banking institutions not providing vision within the markets. Some suggest the Federal government to develop a Green Bank and Green Bonds to off-set these problems for the commercial and housing markets to be granted zero to low interested loans & incentive for the solar industry to compete within the Market. This is no different for other industries which has enjoyed these processes for years naming few Cable Telecommunication Industries , Oil industries, Pharmaceutical industry and etc.

The financial markets are not providing leadership on Solar. We need a different way to approach financing the growth of Solar.

Ultimately, the cost of panels is not really the hurdle to Solar development: The real hurdle is getting financing, permits and PPAs, which are political and financial issues rather than technical ones.

That is what sets successful solar developers apart from road kill. The companies that can position themselves for the next break in any of those arenas, lay-in enough capacity to take advantage, and survive long enough to see the changes will be the real victors.

Cost of Solar PV is now Lowest at $1/Watt peak which means $1000,000/MW only for solar PV it has to be mounted and to improve out pot you might have to have tracking etc all this will increase the cost to be double. It has to be connected to the grid with transmission lines and inverters etc. All this will add costs. This price of Solar cells is from QS Solar of China, FOB China. Cost of Solar panels in India are very much higher nearly $4/Wp. Prices are coming down.. If you use concentrated solar PV you can save on space required.

Key solar points for the reform of the German Renewable Law (EEG):

• Target of 2,500 MW per year, with current indirect quantity control via breathing cap concept to continue (which presently contains a 2,500 to 3,500 MW target corridor in Sec. 20a EEG)
• Solar power is often consumed to a certain extent by the operators themselves (in particular energy generated in rooftop plants). Under the current EEG self consumed power as such is privileged (cf. Section 37 para. 3 sent. 2)

Please take note of the latest development in Germany which promoted Solar Roof top PV with high tariff and high subsidies, with net metering and now taking back through taxes (to cover the common grid expenses may be) and reduction in Tariff measures..... So, we need to learn, notice and make good Karnataka Solar Policy with such well studied activities to create the POLICIES in the Interest of Nation and COMMON MAN.

The charge would not be applied to new units sized 10 kW or smaller. Operators of new fossil-fired plants who consume the power themselves would have to pay 90 percent of the charge. Arizona approved a charge of 70 cents a kW in November, setting a precedent for the US market. In California, where solar already powers 626,000 homes, utilities are pushing for fees to connect solar panels to the grid that would add about $120 a year to rooftop users' bills, a move trade groups say would slow installations.

India established Solar Energy Centre in 1982. They are supposed to build up the knowledge base and advise government to create an ambiance for the growth of solar sector. Their contributions are not in public domain.
How many times engineers and scientists who work on renewable energy visited Western World from 1982 to till now with government funds? Did they report to government on the progress made by Western Countries in solar sector? Global cumulative solar installed capacity is 100+ GW as of 2012.

Considering the stupendous potential of solar source India should give more attention to develop solar sector. India can learn lessons from EUMENA and Asia Super Grid. EUMENA is already on the road. European Union has already decided to limit coal fired plants. 81% of new capacity additions in EU is renewable during 2012.

India has a significant share of 18 GW (6.5% of 282 GW global) installed wind capacity as on 31.3.2013. Onshore wind potential was assessed as 102 GW at 80 metre height by the centre for Wind Energy Technology (2011). In two different studies onshore wind potentials are recorded as 4250 GW and 543 GW. This wide difference in potential assessed require validation before venturing into investment. Present vision is to have 779 GW wind power by 2035. May be an over ambitious target. India should be careful while taking this route.

Applications energized by solar will be adapted and demonstrated.
This will help reduce reliance on subsidy etc.
We are doing the same for hot water - 1st Heat Pump = savings. 2nd After short payback reinvest some savings into Solar Thermal. This takes care of 90% of the daily energy.
3rd. After savings start flowing in, we look at PV to take the Heat Pump off grid.
Result self paying road map for solar.
PV + Heat pump = multiplication of PV output to almost = energy from the Solar Radiation. More Bang for your PV output.

Major challenge for any solar company is winning the confidence of the investors by way of clearly establishing how they stand out from the crowd. Personal rapport in many cases helps the company to get the much needed penetration into the market. Frequent Interaction with the target potential clients at the top most level and educating them on various aspects of solar power projects would only help the solar company to rule the market in the long run.

Be connected with the market and keep them updated about the technological advancements happening in the field of solar power that would help the companies to win the confidence of the investors in the long run.
