Most rooftop PV are not interconnected to the grid. This is the reason why.

Connecting PV to the grid is complicated - no wonder Meralco and other DUI do not interconnect your rooftop to the grid

Renewed Interest in renewables after meeting chairman of WEGEN
Savings from oil and coal importation
This post interest on renewable energy was renewed after meeting Mr. Michael Schefeld, the chair of WeGen. For more than an hour he talked effusively about Renewables in Germany where he comes from, Net Metering (a challenge) In Germany he claims a 60% Renewable acceptance (with solar and wind leading the charge) He showed me the real time increse in renewable usage.
He described the operations of WeGen (engaged in the importation of solar panels, controllers and inverters) I told him about our brief foray into PV and its financing. I broached the feasibility of working together in this promising field. It has been an interest for the last 20 years.
We Gen of which he is the chairman, has partnered with the bishops in promoting renewables (PV) This post observed this to be a unique business model but ultimately financing will be a key component in winning the renewable war.
\He discussed the logic behind the PV ie of that being close to the user, no infrastructure needed like the grid (However it occured to this post that batching may be cheaper in communities to have a farm rather than rooftop installation.
He said that cost of the Solar panels have gone down from $0.40 to only $0.20 (still at P100,,000 per kw)
We planned to meet after the ECQ or MECQ but he died last week. He left a widow whom he endowned with a Filipino Chinese restaurant facing a river connecting Laguna Lake and Pasig River.

First Local Solar Manufacturer in the Philippines
Savings from oil and coal importation
In a recent meeting last week, I met the President of a newly acquired Rural Bank and I found out that they are about to start operations of a local PV manufacturing plant, the first of its kind in the country soon. The plant is capable of producing 200,000 panels a month (that is about 1000 kW worth of panels every month. And half of that would be for export.
The man used to to head a major chemical firm in the country, put up a petrochem plant
He expects mega sales from that. He said that they eliminated the use of silver as a conductor and this means lower lower price.
He promised to email me the prices which he said are way way way low vs imported and China products
I said that with the rural bank, we can provide solar financing that is affordable

World's Largest Solar Power Plant Shams 1 in UAE goes on line
Repost from Livescience by Marc Lallanila | March 13, 2013
One of the world's largest PV power plant, Shams 1, located in UAE goes on line. The capacity of the PV plant is enough to power 20,000 homes and remove 175,000 tons of CO2 a year, or remove 35,000 cars off the road. There will be another planned l00 mW in KSA by the end of the year known as Noor l. Saudi Arabia plans to have 100 per cent renewable energy by 2022; Qatar's target is 1.8 gW by 2014.
UAE uses CSP technology (concentrated solar power.) Mirrors focus suns rays to create steam which runs steam turbines. The plant has 258,000 parabolic mirrors spread over an area of 1 square mile (2.5 square km)
Why would a country producing energy invest heavily in renewable energy? So that it does not use its own output and sell more oil.
Very practical and makes good economic sense

Will natural gas boom stall solar PV /Renewables?
Repost from The great energy challenge blog from Nat Geo | Feb 22, 2012
Fracking and boom in Bakken North Dakota shale wells has resulted in all time low price for natural gas. However, this is unlikely to continue over the long term because of: regulation, underperformance of some of the wells, and on the demand side: export of CNG, use of NG for electric power generation should drive the price soon.
Boom in PV production has resulted in PV panel cost o $0.70 per watt (this is for crystalline panels - the industry standard)(this used to be $8.00) and comes at parity with natural gas. Installed cost will be at $2.70 for commercial and $3.60 for residential.
Grid electricity continues to rise despite decreasing whole sale price.
Thus the low natural gas price and will not affect the long term viability of solar energy
