The document summarizes the results of a social impact evaluation conducted by Hybrid Social Solutions, Inc. (HSSi) over the summer. It conducted 103 interviews (37 pre-purchase, 66 post-purchase) across three regions in the Philippines. The evaluation found that after purchasing HSSi solar lights, customers saved on average 134 PHP per month on energy, spent 3.23 extra hours per week on education, and felt 11.75% safer from burns. Customers also reported benefits like brighter lighting, more study time for children, better air quality, and an ability to charge phones during blackouts.

2. 1. What We Wanted To Do
2. What We Accomplished
3. What We Designed
4. What We Learned
game plan:
4. ü Design a system so that HSSi can
gather and analyze social impact data
regularly.
ü Test it out (and update what we know
about HSSi’s social impact in the
process).
two objectives:
6. why do we even care about
social impact evaluation?
so…
7. DATA
Shows our partners how our
products help them reach
their goals
Helps us improve our
technical support systems and
marketing
Gives us “street cred” with
funders and other social
enterprises
Makes us happy by showing
us that what we do matters
9. PREPARATION• Researched what other solar companies evaluate, what
HSSi has evaluated in the past
• Wrote a new version of the survey
• Developed a field research plan for the summer
• Coordinated with branch managers to find interpreters
11. challenges:
• Timing is tough. To get the pre-purchase interviews, we
have to meet customers after they sign up for a light but
before they receive it. Getting to them in that timespan is
tricky and requires tight coordination with loan officers.
• Distance can delay. Because many of our customers live in
rural areas, it takes time to get between meeting centers,
limiting the number of interviews we can do per day.
• Absences happen (a lot). While the plan was to meet up
with pre-purchase respondents after a month for post-
purchase surveys, many were not at group meetings when
we went back. We found some of them, but not many.

DATA COLLECTION & ANALYSIS PROCESS
17. challenges:
• Timing is tough. à Every afternoon, check in with the next
day’s loan officer to develop a list of customers who have
recently started paperwork to purchase one of our products.
• Distance can delay. à Map barangays at the beginning of the
research round and plan shortest distances in an area each
day. (This one is tough to mitigate.)
• Absences happen (a lot). à Cell phone numbers will be
critical for reminders the day before post-purchase interviews.
If a customer does not have a cell phone, ask for a neighbor’s.

24. Before the light, we
paid for kerosene, charging
large batteries, and
charging our cell phones.
Now, we save all of that
money. After we pay for the
solar light, we can buy
more food. We have so
much more and better
food now.
“
”
25. My 5-year-old
granddaughter is so
amazed by how bright
the light is, and it cut our
electricity bill in half. It
brought me the luck of
money -- my pockets
were empty, but now I
can fill them again. With
the money I save, I can
buy lipstick!

28. 3.23
HOURS
respondents reported
an extra
of study per week
after purchasing HSSi solar.
(…and 47.6% of post-purchase
respondents reported using
only solar for children’s study.)
33. I use my solar
light when my baby
wakes up at night so
that we can see him
and so that he feels
safe. It also helps
me breastfeed him
at night.
“
”
36. Respondents felt 11.75% safer from
fuel-related skin burns after purchase of a
solar light (from 59.5% to 71.2% safer).
37. When a brownout
occurs, my children
don't panic because it's
not hard for them to look
for the light -- the button
lights up so that it's easy
to switch it on. It's also
easy to use when my
child needs to go to the
comfort room at night--
he can now manage
without me.
“
”
38. I don't like to
sleep in bright light
or in total darkness,
so I'm very happy
that this light has a
dim setting. I keep it
on all night, and it's
safe when I fall
asleep reading the
Bible or praying
before bed.
“
”
42. We use the solar
light for our piggery --
when the pigs give birth,
we use the lamp. With
kerosene, the lantern was
always tipping over. My
husband bought a cheap
solar light from the
market, but it broke. Our
HSSi solar light is much
better -- we trust the
quality more.
“
”
43. The light is
important to me because
it charges my cell phone
in brownouts. My
husband works in Manila,
so having a phone for
communication is very
important to us, and with
solar, I can always
talk to him.
“
”
44. Customers listed the most important advantages of HSSi solar lights:
ü feeling safer in emergencies
ü brighter light in their households
ü lower bills from electricity / other energy sources
ü more reliable light
ü easier to charge cell phone
TOP BENEFITS
Out of 66 interviews, only two respondents could come up with
disadvantages to owning HSSi solar: one wished the light were less
yellow, and another wished it would turn off automatically.
TOP DRAWBACKS
45. On average, HSSI’s solar lights increase the time customers have per week for:
MORE HOURS IN THE WEEK
ü work / job (12.5 h)
ü socializing (9.7 h)
ü chores (8.4 h)
ü religious activity (2.7 h)
ü cooking (3.7 h)
ü study (3.2 h)
46. Before when we
didn't have it, we had
to close our store every
time there was a
brownout. Now, we're
always open. Plus, the
air in the store is
cleaner because there
is no more smoke
from lanterns.
“
”
47. When my
husband gets
coconuts, we use the
solar light to process
them at night. We’ve
been able to improve
our income because
of extra working
hours at night.
“
”
49. We don't have
electricity because my
neighbor doesn't want
to let us connect to
their cable, and before
that was a big problem
for my family. But now
with solar, that same
neighbor asks why we
have light even in
brownouts!
