Residential Solar System

I installed it in Sacramento City(California) and the inspector gave us a correction notice because he wanted us to directly connect the array to the ground using a grounding conductor directly into the ground. The wierd thing is that it is already grounded back at the panel…. Has anyone had to do this before? We haven’t been required to do this until now. I would appreciate it if you could state what code might be able to be used to fight this. Thank you if you can help.

i know its a stupid question, but explain please

graduated in Electrical and Electronics Engineering 2011 and My training at infosys starts at 8th August 2011.
I have a passion to work in my core area. I am currently looking for job in my core area. Due to financial crisis, i must go to work within a month and repay my Educational loan and the Bond at Infosys is for 1.5 Years. But i heard through my friends that Training at Infosys is world class. I am really confused wheather to go to infosys, and stay there for one year till the bond ends or search for core job.

My Papers and projects include,

Two international conference papers:

1. Efficacy Of Symmetrical Multipulse Modulation In The Single-Phase Matrix Converter Topology.

2. Performance analysis of three phase PWM AC chopper feeding a delta connected load.

Main projects:

1. Power quality assessment in Three-phase matrix converter.
2. Performance analysis in HVDC bipolar link.
3. Unity power factor operations of a AC-DC converter feeding a DC drive based on Hysteresis current control technique.
4. Selective harmonic elimination in a Three-phase AC chopper based on Multi-pulse modulation.
5. Automatic sensorless dual axis solar tracking system.

Term projects:

1. Line follower two-wheeled robot.
2. Real time localisation of a mobile robot using Webcam.
3. PWM based speed control of DC Motor using PIC Microcontroller.
4. Residential automated water management system.
5. Stress level indicator (EEG).
6. External pace-maker (ECG).
7. Robotic arm for disabled Person (EMG).

I have a UPS (Power backup at home). it is
1000 watt
185 Amp battery (Standard Liquid acid battery like in car)
my ups charges at 10-20 Amp..
How much power of solar cell i need in order to charge my batteries
it would be helpfull if u can tel me the formula to calculate :p

i have no electricity
yeah there is !!!!!!!!!!!!!!!!!!!!!!!!!!!!! expensive

What would be a good price for either?

So I’ve been a little confused about the solar rebates for residential systems. Based on my understanding, my municipal provider (SMUD) will pay .55/watt http://www.smud.org/en/community-environment/solar/Pages/index.aspx and the federal rebate is 30%. This seems too high to me. I can buy a 7000w grid tied system (complete minus mounting brackets) for ,000. This means that 7,000w x .55/w = ,850

For the federal rebate, they will pay up to 0 per .5kw So this means 7000/.5kw x 0 = ,000

This would come out to ,850 in total rebates, sounds too good to be true. So, my question is, what am I missing? I would be installing the system myself (following all local codes and the system would be checked and signed off by a certified solar technician) but even then I would come out close to even. Can anyone shed some light on what I’m missing here??

Thanks!

I am looking to make my own solar panels and have on offer to buy this book. Power 4 Home book for . I am wondering if this is a scam? or if it is worth it to buy this book. Thank you
If you know any sites that tell you how to do it, please provide site

Using all tax credits, rebates and incentives, it seems to me that a residential solar system would be the most sound economic decision when considering the life of both.
