The foreign observer did not read SEDA vision.
SEDA focus on promotion of renewable energy development. Solar PV is the easiest renewable energy source available for public. SEDA wants renewable energy awareness among public. Solar PV apparently the best choice.
For example, when you installed at your house, your family (assume 4 persons) will learn bout solar pv as renewable energy. Then, your neighbors learned as well (assume 2 houses with 8 pax). Later, the whole Taman will know solar panel on your roof (This can be 500 pax).
One installation will create 500 rakyat awareness in renewable energy.

The biomass, biogas and small hydro can contribute much higher generation but the impact on renewable energy awareness is minimum. The workers in these renewable energy plant will know but anyone outside will not know.

Anyway, BIG SALUTE to pioneer of malaysia renewable energy producer in Suria1000 and SREP program. They started before FiT

to make it awareness and benefit more people, highly propose streamline the installation to DIY level, standardise and ease the application.

solar panel, inverters, and accessories nowadays are getting cheaper

RM800 for a 300W solar panel expensive?

depends on your volume. if 1-2 pieces, this price  is OK.
if buy more, many better choice out there.

how much an inverter cost in market which can handle 9kWp system? any suggestion and notes need to know when buying such inverter? any spec and certification needed for Malaysia ? thanks notworthy.gif

From my understanding, 9kW inverter is uncommon but you can use 8kW inverter. It is good to undersize your inverter by 10%.
Any suggestion for spec? Put aside brand and focus on spec and standards. You can go to seda website to download 2014 testing and commissioning requirements for PV system. You will find all necessary standards in the doc.

I have 8.8kWp installed and I am using 10kW inverter.  Due to odd roof shape, I have one string configured as 5.2kWp and another string with 3.6kWp.  I realize that I am not operating at maximum efficiency of the inverter but I could not find any single inverter with lower power rating that can handle 5.2kWp string.  I do not have room for 2 inverters.

how much for your inverters? notworthy.gif

seda may be asked to reform their registration method to random drawing instead of letting sp to jam or block the registration. which is unfair to other applicants.

by then, new battery comes out already
good and cheap enough to generate electricity and reuse at own house, no need to sell

Well, the good news in today's announcement that they are honoring the que numbers given. The uncertainty is that weather this 1000 will all fill up the 8MW allocation or by the time they get to que number 800, maybe the 8MW already finish...

The big question is, what happens to this 200 ppl who will get priority in the next quota, but next quota is ballot allocation, so how?? Really big question..

I am just hoping that I get this 8MW allocation... Just have to wait for the announcement...

SEDA may change the system

they know the UNFAIR system previously, who submitted earlier on the date of release quota who would get the quota.
this allows speculation and SP jammed the lines to submit application.

do suspect SEDA may be suspended this project earlier if the current TNB popping more tariff on normal consumers.

anyway, 3 yrs later, new battery will be cheap, safer and more efficient, off-grid may be a big issue to TNB monopoly role. perhaps TNB should announce more strict rules to protect themselves in energy supply role. e.g. generating solar energy and store in battery to use is ILLEGAL! rclxms.gif

Failed too.. My application sat in SEDA's database since Dec 13 - purged in May 14 to make way for que number system.
The outcome is failed to get que number..  because SEDA server got overloaded with http request.

My SI returned my deposit..  I thought the application was first submit first approved.. but they changed to que number system (with mediocre server specs) now they want to do online balloting...  No need lah online balloting - go to auditorium  and use ping pong balls in a big glass bowl lagi transparent.  doh.gif

btw tesla opens up their battery patents, heard that off-grid solar system battery design may have a big thrill and cost cut-throat game soon.

tnb may have more dilemma in the next 5 yrs if battery cost cut throat in off grid solar system.

any body read the terms and conditions if tnb stops to buy back electricity earlier than the contracts made?

Still a long way to go...

Tesla's battery charging and Charging control patents allows low voltage to speed charge a car in 1 hr and run 500km.

one of the good designs from their battery charging patents is on the individual battery cells charges, temperature, stability, safety and efficiency control and management.

simply like the above few patents(opening free soon) will significantly change the off-grid solar system and cost of solar system.

material science and exploring the cells never stop so far, it may be far away from now but at least what we will have a big change soon is from Tesla's opening patents.

how you think if we can fully charge a house solar cells battery within 3 hrs every day and let your whole house use if for a day or longer at a cost of 30% of the current price?

if we can see the manufacturers at china have the evidence to adopt the above patents to make new solar system, you may expect it a new era in the market. rolleyes.gif

installation slow down due to the quota released after year
so what are those companies do now in this period?
any ISP care to share?

australia just announced and tested by US organisation that they have invented solar panel which has 40% efficiency. the design breakthrough is mainly due to the optical filtering technique.
it means that all the current solar panel may need to retrench in the next 2 yrs.
energy authorities may impose the efficiency on the solar panel standard when commission to the grid.

It is unlikely for current technology solar panels to be retired in 2 years as the process of commercialisation takes years.

The current solar panels were first invented in the 1970s and it has taken over 40 years for it to reach commercial consumer affordability.

Last year, there was an announcement by Singapore researchers (http://media.ntu.edu.sg/NewsReleases/Pages/newsdetail.aspx?news=8f1a9f10-d53a-4d0b-8917-72593de75029) of better yielding solar panels but not sure what has happened to it.

The process of commercialisation is a long and arduous one, dictated by demand and price.

And the report of the 40.4% efficiency of the Australia result was done with a solar tracker. (http://theenergycollective.com/eric-wesoff/2168891/world-record-solar-module-efficiency-404-cpv-startup-raygen).

A solar tracker will add to your start up cost.
*
it is not in lab, research level, the product has verified and proven by US energy authorities but you still can use your traditional logic to count.

adding the low oil price recently, china solar panel manufacturers may start to lower the price further.
your link is not related to the one we read. it is not solar tracking to improve the eficiency. that's ages ago topic

what if seda required the coming panel installation must reach certain efficiency in yield like 40%, then they can buy some time to allow more "cheaper oil" to spend first. smile.gif
