Running a bedroom on solar power ?

    Hi guys, just wondering where to be looking for something to run a bed room with a tv 42inch lcd , netbook, radio, light, router, digi box.

    The netbook would need near, 80% uptime same with the router. TV is not used that much say 1-2 hours max every 3days ..

    Although I said solar power, I would consider any other type of energy source available to me IE wind power.

    Suggest you get an electricity monitor and see what the total energy requirement is in KwHrs per day. Then you can calculate the necessary PV size required for this.

    Wind would work if you have a suitable site, but it seems your requirements are quite modest overall. Probably about 2.4KwHrs per day. Wind is usually grid tied rather than battery based. Is this to be off-grid, or are you just offsetting your consumption? If off-grid, probably solar would be cheaper for your needs.

    Retscreen does a free software package that can estimate the output of PVs for any geographical location. You need to take the worst month and add about 20% for battery losses and a further 10% for inverter losses.
