It's all about flower symbolism in this Flower Meanings Chart. Don't forget. Whatever flower gift you put together, send along a card, a note, a letter, a plaque, a personalized inscription on a mirror, a caption, SOMETHING that explains why it is you are giving them what you are giving them. They need to know your feelings through the flowers.
Solar Panels. The solar panels themselves usually account for about 30% of total costs. Residential solar panels with a combined capacity of 3-8kW typically cost between $4,000-$16,000. The best solar panels are not necessarily the most expensive.
Solar Power Cost Per kWh. A useful figure to use when looking at solar is cost per kWh, as this can be directly compared to your current power bill. A National Renewable Energy Laboratory report spanning 7 U.S states, gives a levelised cost of solar of between $0.28 and $0.46 per kWh for residential solar systems. Lawrence Berkeley National Laboratory research paper shows that among 58,000 installations in various California solar initiatives, the average cost of solar panels dropped from $12.15/watt in 1998 to $8.09 in 2009 [4].
