Use a thin film array (easy install) and a micro inverter (cheaper, lighter and works better in cloudy location).

So how much electricity will this produce?
So if your have your 300W solar panel in New York (where solar irradiation = 4.49kWh on average annually according to the table), it will generate (4.49kWh x 0.3kW =) 1.347kWh for the day.
So I could in a month produce 30 x 1.347kWh = 40.41kWh
GMP charge $0.14959/kWh so each month I would in theory be generating $6 worth of electricity.
Investment $1200/$6 = 200 months / 12 = 17 years to pay back :-(
The total cost of the system would have to fall to around $500 per each of these to be worth it in my opinion.

King of Thrones - UBS OPTIMUS FOUNDATION’S WASH AWAY GAME CHALLENGE
In the Southern Indian state of Tamil Nadu, five phones exist for every two toilets. Even in areas without toilets, a lack of understanding about proper use has led to 60 percent of the population practicing open defecation. This practice is so commonplace that most alternatives are widely rejected and are even seen as unnatural.
When UBS/Optimus extended an invitation to game developers to create a game that could impact this behavior and begin to promote toilet usage, I was immediately intrigued. Could I apply the same levers that I've seen work int he world of fitness to this problem? The result was a game concept that I'm calling "King of Thrones"
King of Thrones
Basically I've taken levers like social inclusion and recognition, activity journaling and ownership and combined them into a "game" that can be thought of as Foursquare for toilets :-)
King of Thrones Use Case
Sam passes by a toilet station on the way home from school. Each day she checks in from her phone by pressing the check in button once when she enters the toilet and then again 120 seconds later when she exits. The GPS on her phone determines that she has complied with the rules of “check in” and awards her a point for that toilet session.
Her game screen informs her that she is on the way to becoming the king of this particular “throne” for the following month by presenting her personal avatar in a ranked fashion along with other toilet users. Since Sam has already used this check in procedure 5 times this month, each of her check in’s is now awarded two points – accelerating her ascent to the top of the ranking.
By the end of the month, Sam has been recognized as the official King of that throne and as such gets to choose the avatar that will appear on the toilet maps for that toilet, as well as the name of that particular toilet. Avatars and names are designed to tie into current themes and trends among the youth population and would include references to sporting figures, fantasy locations, movies and cultural icons.
Sam is also able to report on the condition of the toilet, call in maintenance or cleaning services or be compensated for personally maintaining the toilet herself.
Next steps?
Should this concept be chosen as a winner (a long shot at best) I'll have an opportunity to see it in action.

Dean Potter wasn't a poser... but you are
Dean Potter died. I knew moments after it happened as my facebook feed, news feed and twitter accounts blew up with posts, reposts and heartfelt "I'm so sorry for your loss" posts and tweets and comments.
Maybe a more kind hearted soul would have felt the same impulse to post and comment and share and join in the tear filled chest pounding self flagellation that will consume the climbing community for weeks to come but I just can't muster it - because here is the thing. I didn't know Dean. I didn't know his friends and family and I've never met him.
Since I started climbing over 30 years ago the community I consider myself a part of has lost dozens of the most daring and selfless - unknowns like Derek, well knowns like Bachar and Dan and Alex and the obscure like the poor bastard I watched gasp out his last moments on earth splattered half in and half out of the Mississippi on an achingly beautiful mother's days.
Each time I've watched the "core community" come together and make heartfelt tributes to the fallen - beating their chests in an effort to out grieve each other. But here is the thing. Behind closed doors and in the quiet of the night we all know that none of us are truly worthy. Dean put his life on the line and crossed it in the pursuit of his dreams - demonstrating a commitment in the process that we will simply never know. Wifes, kids, debt, parents, dependents and life prevent the vast majority of us from committing our lives in such a fashion. We post and grieve publicly not to comfort Dean's loved ones, but to draft behind those who have demonstrated and proved once again that our sport is truly "rad", "extreme" and really really dangerous. Dean's death allows the rest of us to bask in the knowledge that we are cheating death each time we set out to climb - when in reality our bolted lines and cam cracks aren't much more dangerous that running around a city block.
Compounding all this is the fact that lurking just out of sight are the sanuk organic cotton styly sunglass wearing uber groovy marketing directors who either consciously or unconsciously lick their collective chops each time another tragedy strikes. Death sells, risk attracts. Red Bull will sell even more shit to posers who have trouble climbing out of their xbox couches, Patagonia will sell more overpriced crap to Newbury street shoppers looking to be "authentic" and climbing gyms around the country will attract more daisy chain shiny gear wearing dudes and dudettes.
I'm sorry Dean died and I wish I had met him if only to shake his hand and wish him luck. At the same time I can't shake the guilty feeling knowing that his death and the death of countless others contribute to the popularity and attraction of the sport I love.
RIP Dean.
